The study analyzed the prospects and challenges of community-based grassland management (CBGM) in Yanchi County of Ningxia Hui Autonomous Region, China, using the strengths, weaknesses, opportunities, and threats approach combined with the analytic hierarchy process. Preference data were used from three stakeholder groups, namely, community, government, and academia, all of which are very familiar with Yanchi County. Representatives of local communities and academia perceive that the strengths and opportunities for CBGM outweigh its weaknesses and threats. However, representatives of government agencies hold an opposite view, as they anticipate that threats associated with the CBGM approach have the highest weight. We suggest the CBGM be implemented firstly in small villages, and then promoted in larger areas in the future.  相似文献

Iran has very high potential for production and export of dimension stone (rock quarried to size and shape specifications); nevertheless, in spite of growing mine production during the past decade, in many instances this potential has been overlooked. Construction, decorative, and facing stones of Iran are among the highest-quality products in the world. In this paper, Iran’s dimensional stone mines are analyzed using strengths, weaknesses, opportunities and threats (SWOT) analysis in combination with analytic hierarchy process (AHP). SWOT analysis is a tool commonly used for analyzing both the internal and external environments in order to attain a systematic approach and support for a decision situation. Conventionally, SWOT analysis is qualitative and does not quantify the effect of the factors. Consequently, it is not effective in priority setting. To overcome this limitation, SWOT analysis has been used in combination with other quantitative multi-criteria decision making methods especially the AHP. In this study, first an environment analysis was performed by an expert team familiar with these mines. In this way, the SWOT factors were identified and the subfactors which had very significant effects on the success of these mines were determined. Using the SWOT subfactors, the SWOT matrix and alternative strategies based on these subfactors were developed. Subsequently, the strategies were prioritized and the best strategies for Iran’s dimensional stone mines were determined.  相似文献

The Iran’s mineral sector, as a major supplier of mineral industries, plays a central role on Iran economy. Promoting the productivity in this area leads to the enhancement of the business environment. Also, it can influence the production chain and minerals value added. In this study, a comprehensive study was conducted on the major barriers/drivers factors affecting the efficiency in the mining sector. Furthermore, 16 key factors were identified using the expert views. These parameters are divided into four main categories: strengths, weaknesses, opportunities, and threats. In addition, a hierarchy model was designed in which the mentioned four efficient strategic parameters were implemented and the SWOT analysis was applied, as well as the nine macro strategies were determined. In order to prioritize these strategies, multiple steps were carried out. First, the subfactors were weighted by implementing the fuzzy multi attribute decision-making technique by combining the experts’ views and triangular fuzzy numbers. Subsequently, the strategies were prioritized by employing the group Fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) model. The sensitive analysis of the results presents some minor changes in score of the alternatives, but no alteration was affected in the prioritized strategies. The results revealed the importance of resource allocation strategies related to the existing investments as well as supporting and facilitating the new technology in the mining sector.  相似文献

Coastal area is the region with the highest degree of economic and social development and the largest ecological stress in current China, where the proportions and the spatial patterns of developed coastal resource and environment are determined by projects planning. Ecological carrying capacity evaluation is the necessary prerequisite for sustainable utilization of natural resources and protecting ecological environment to ensure healthy and sustainable economic and social development to project planning. Based on the pressure types of projects planning on resources and environment, the concept and contents of coastal ecological carrying capacity were redefined for enhancing the practical value of ecological carrying capacity evaluation. The domestic and foreign research progress and advances related with coastal ecological carrying capacity evaluation were reviewed, which included habitat suitability evaluation, suitability assessment of construction land development, reclamation suitability evaluation and assessment of sea water environmental capacity. The conclusion noted that domestic research of coastal ecological carrying capacity needs to build a complete system of ecological carrying capacity evaluation methodology based on extensive reference to foreign research results, and quantitative evaluation and spatial visualization research related with coastal ecological carrying capacity should be carried out to provide strong support for ecological civilization process of economy and society in coustal areas.  相似文献

Land, Sea and Human Effort was the central theme of the 28th IGU Congress in The Hague, The Netherlands. This volume contains the key-note addresses highlighting this central theme. Three major issues regarding low-land coasts came to the fore: land-use, environmental quality and safeguarding of the land. An interesting question is whether the concentration of human activities in large urban nodes will continue, or that such nodes and hierarchies will no longer structure our world, because of the ever-increasing importance of all means of communication and transport, as indicated by Johnston. Functions may disperse to specialised environments. A similar specialisation may be encountered in e.g. the development of tourism in the coastal zone. As Gormsen has elucidated, tourism has over time extended in a sequence of spatial peripheries. Consequently, phases in development may be identified with a growing impact and participation of local tourism interwoven with international growth. The environmental quality of coastal zones is seriously under threat, due to ever-increasing population pressure and human exploitation. The major problems are pollution and the availability of good quality water. Oudshoorn explored the worlds resources of drinking water, indicating the great need for political awareness of this huge problem. Cross-sectoral planning is advocated by Oudshoorn, even if water management often trespasses international boundaries and the harmonisation of the planning strategies is mostly difficult. The environmental quality of the coastal zone is also affected by the exploitation of oil and gas resources. Odell demonstrates that the conditions for this exploitation in the North Sea are unique, especially because of the great impact of an international agreement on offshore exploitation. Planning in sea areas is becoming an issue of increasing importance as it has to cope with the many, often conflicting interests, such as shipping, fishery, mining, waste disposal in relation to environmental and ecological constraints. The safeguarding of the land against river floods and sea side storm surges under the threat of a rising sea level is another important issue in coastal low-lands. Callander reviews the present state of human influence on climatic change and the associated sea level change. As indicated by Hesselman et al. new remote sensing and associated GIS techniques have recently been developed which are a great contribution in determining the fate of the coastal zones with respect to the threats induced by natural and human activities.  相似文献

The monitoring of plans in a strategic context aims to do more than accumulate and corroborate breadth and depth of all information requirements of a complex organisation. Strategic monitoring, whilst including the quantitative role of gathering facts to improve analytical decision-making, is necessarily qualitatively involved with the fostering of relationships with various tiers of authorities and associations, and with environmental groups. The system requirements of qualitative monitoring are not always as reliant upon specialised, sophisticated computer monitoring as upon flexible organisations of internal staff who are encouraged, at the earliest phases of decision-making, to investigate the deficiencies and criticisms of county plans. Qualitative monitoring is a more sensitive instrument for determining how politics affects planning, and vice versa, and for gradually reconciling conflicts. The nature and extent of both approaches to monitoring are here examined in the cases of two U.K. county planning departments.  相似文献

The salinization of freshwater-dependent coastal ecosystems precedes inundation by sea level rise. This type of saltwater intrusion places communities, ecosystems, and infrastructure at substantial risk. Risk perceptions of local residents are an indicator to gauge public support for climate change adaptation planning. Here, we document residential perspectives on the present and future threats posed by saltwater intrusion in a rural, low-lying region in coastal North Carolina, and we compare the spatial distribution of survey responses to physical landscape variables such as distance to coastline, artificial drainage density, elevation, saltwater intrusion vulnerability, and actual salinity measured during a synoptic field survey. We evaluate and discuss the degree of alignment or misalignment between risk perceptions and metrics of exposure to saltwater intrusion. Risk perceptions align well with the physical landscape characteristics, as residents with greater exposure to saltwater intrusion, including those living on low-lying land with high concentrations of artificial drainages, perceive greater risk than people living in low-exposure areas. Uncertainty about threats of saltwater intrusion is greatest among those living at higher elevations, whose properties and communities are less likely to be exposed to high salinity. As rising sea levels, drought, and coastal storms increase the likelihood of saltwater intrusion in coastal regions, integrated assessments of risk perceptions and physical exposure are critical for developing outreach activities and planning adaptation measures.

Rather than being abandoned along with the demise of the centrally planned economy, city planning as a profession is flourishing in China. New hybrid plans such as strategic development plans (concept plans) have been invented, and the planning procedure has become more flexible. Design competition and planning consultancy are widespread. This paper examines the development of new strategic development plans and design competition. It is argued that city planning has been re-orientated from a technical rationale, i.e. allocating state development projects to the city, to the imperative derived from market-oriented development, i.e. consolidating competitiveness during inter-city competition. The contradiction between market and planning is that while the status of city planning has been raised and its approach is becoming more strategic, the actual functionality of city planning has become more instrumental.  相似文献
