贫困问题一直是中国政府致力解决的社会问题,随着中国经济的发展,扶贫业绩显著,贫苦人口的分布也转变为"广而散,小而集中",呈现出碎片化分布的特点。针对"精准扶贫"政策实施过程中出现的贫困户精准识别、管理、帮扶、考核、预测等问题,提出了基于GIS的扶贫空间数据可视化、空间分析以及预测模型,对扶贫工作进行更好的规划、决策和预判。为此将GIS技术与"精准扶贫"政策进行了有机的契合,开发了基于GIS的精准扶贫管理平台,通过研究导致贫困的各种因素和障碍,初步对贫困的发展趋势进行预判,达到了可持续脱贫的目标。对贫困户建立的完善的帮扶追踪机制,扶贫监督管理方案,为"全民脱贫"目标奠定技术依托。使得扶贫工作的针对性更强,有效性得到改进,为后期扶贫攻坚打下良好基础。 相似文献

界定生态产品概念、探索生态产品的价值,是实现生态保护、生态补偿以及生态扶贫的重要举措。探索县域森林生态系统的资源资产核算,有助于利用良好的森林生态资源,开展林业生态扶贫。本文以国家级贫困县——重庆市城口县为例,初步研究了森林资源资产核算方法,结果表明:1)城口县森林资源资产评估总额达到577886.48万元,远超其年均GDP;2)城口县不同乡镇森林资源资产表现出极大的分布差异,现有树种的资产量分布也极不平衡,栎类总资产达到357133.1万元,占全县所有乔木资产的62.2%;3)城口县森林生态服务价值总计487097.58万元,涵养水源、保育土壤是主要生态服务功能,中熟林与近熟林体现了主要生态服务价值。 相似文献

Irrigation infrastructure development for smallholder farmers in developing countries increasingly gains attention in the light of domestic food security and poverty alleviation. However, these complex landscapes with small cultivated plots pose a challenge with regard to mapping and monitoring irrigated agriculture. This study presents an object-based approach to map irrigated agriculture in an area in the Central Rift Valley in Ethiopia using SPOT6 imagery. The study is a proof-of-concept that the use of shape, texture, neighbour and location information next to spectral information is beneficial for the classification of irrigated agriculture. The underlying assumption is that the application of irrigation has a positive effect on crop growth throughout the field, following the field's borders, which is detectable in an object-based approach. The type of agricultural system was also mapped, distinguishing smallholder farming and modern large-scale agriculture. Irrigated agriculture was mapped with an overall accuracy of 94% and a kappa coefficient of 0.85. Producer's and user's accuracies were on average 90.6% and 84.2% respectively. The distinction between smallholder farming and large-scale agriculture was identified with an overall accuracy of 95% and a kappa coefficient of 0.88. The classifications were performed at the field level, since the segmentation was able to adequately delineate individual fields. The additional use of object features proved essential for the identification of cropland plots, irrigation period and type of agricultural system. This method is independent of expert knowledge on crop phenology and absolute spectral values. The proposed method is useful for the assessment of spatio-temporal dynamics of irrigated (smallholder) agriculture in complex landscapes and yields a basis for land and water managers on agricultural water use. 相似文献

Poverty at the national and sub-national level is commonly mapped on the basis of household surveys. Typical poverty metrics like the head count index are not able to identify its underlaying factors, particularly in rural economies based on subsistence agriculture. This paper relates agro-ecological marginality identified from regional and global datasets including remote sensing products like the normalized difference vegetation index (NDVI) and rainfall to rural agricultural production and food consumption in Burkina Faso. The objective is to analyze poverty patterns and to generate a fine resolution poverty map at the national scale. We compose a new indicator from a range of welfare indicators quantified from Georeferenced household surveys, indicating a spatially varying set of welfare and poverty states of rural communities. Next, a local spatial regression is used to relate each welfare and poverty state to the agro-ecological marginality. Our results show strong spatial dependency of welfare and poverty states over agro-ecological marginality in heterogeneous regions, indicating that environmental factors affect living conditions in rural communities. The agro-ecological stress and related marginality vary locally between rural communities within each region. About 58% variance in the welfare indicator is explained by the factors of rural agricultural production and 42% is explained by the factor of food consumption. We found that the spatially explicit approach based on multi-temporal remote sensing products effectively summarizes information on poverty and facilitates further interpretation of the newly developed welfare indicator. The proposed method was validated with poverty incidence obtained from national surveys. 相似文献

GIS is increasingly used in poverty mapping but there is no generic data model for database development. Examples exist already of industry‐specific models. Having such a data model eases the complexity of incorporating spatial data in poverty assessments. This article raises awareness about the need for a generic poverty data model for use in poverty mapping. It seeks to stimulate a lively debate that will lead to the development and adoption of such a data model. The ultimate goal will be to get to some level of standardization for common data types that would facilitate spatial data use in poverty assessment and sharing among poverty projects. This article is a first step at developing a data model for poverty mapping at a conceptual level. Handling multidimensional social problems, such as poverty, using a spatial framework can be challenging because of the myriad of poverty indicators in use. Employing the entity‐relationship approach, a conceptual model is developed in the current article that identifies the key thematic layers, entities, and relationships. The conceptual model produced is useful for modeling the content of the database for use in assessing and monitoring poverty. 相似文献

This paper focuses on the public participation in environmental planning. After the decade for inaccessible information related to the decision taken, actually, the program of public participation is the reference of all the decision making process. However, there are some factors that limit this process, such as poverty, illiteracy, ignorance and often the social inequality. Therefore, this study focuses first on the benefits of public participation in environmental planning, then the involvement of the local population, and finally the decision making access using a case study of Madagascar. 相似文献
