Spatial justice and the land politics of renewables: Dispossessing vulnerable communities through solar energy mega-projects     

《Geoforum》2016

This paper considers aspects of spatial justice in the processes of land acquisition for large-scale solar energy projects in the developmentalist context of India. It explores the case of one of the world’s largest solar park projects in Charanka, Gujarat. While the official rhetoric suggests an inclusive project for globally benign renewable energy production, the research reveals a more controversial land and power politics of renewable energy. It is argued, in particular, that the project increases the precariousness of vulnerable communities, who are exposed to the loss of livelihoods due to the enclosure of common land and extra-legal mechanisms through which land acquisitions for the project have reportedly taken place. This case exemplifies how solar mega-projects may manifest a regime of accumulation whereby low-carbon coalitions of interests can maximize their gains by dispossessing vulnerable social groups of their life-sustaining assets.  相似文献   

顾及等级的城市公园绿地空间布局合理性分析     

朱腾  程钢  万意 《测绘科学》2016,41(12):136-141

针对简单两步移动搜索法忽略资源辐射范围差异、对所有资源采用相同阈值范围的缺点,该文依据公园建设的不同标准对研究区域内的公园进行分类,为不同等级的公园设置不同的搜索半径,使得模型与现实情况更为相符,结果更为可靠。以深圳市龙岗区为例,综合运用距离分析、面积分析和改进的两步移动搜索法对研究区域的公园布局评价,评价结果较好地反映了龙岗区公园的布局情况。  相似文献   

基于改进高斯两步移动搜索法的深圳市公园绿地可达性评价   总被引：2，自引：0，他引：2

公园绿地可达性是衡量城市宜居水平的重要指标。针对传统可达性分析多用统计数据开展评估而导致的供需尺度失衡问题,论文以深圳为例,采用公园绿地空间矢量数据和手机信令数据获取供需空间分布,采用高斯两步移动搜索法计算交通小区(TAZ)尺度公园绿地可达性,并结合可达性结果及供需、交通情况聚类,剖析可达性差异化模式及成因。主要结论如下：① 通过改进传统可达性计算数据源和高斯两步移动搜索模型,建立城市中微观尺度公园绿地可达性评价及成因研究框架,可更精确地评估优化城市公园绿地可达性;② 深圳市公园绿地综合可达性整体水平较高,但存在明显的从中心向外围递减的趋势,社区公园可达性差异与公园绿地供需不匹配是造成各区域可达性差异大的重要原因;③ 根据K均值聚类分析结果,将深圳市TAZ单元分成低供给低需求低可达性区、中供给低需求中可达性区、高供给高需求中可达性区、高供给低需求高可达性区,各类区域具有差异化的可达性内涵、特征和成因;④ 公园绿地可达性提升可针对不同分区特征,通过公园布局优化、道路建设和居住区规划布局等差异化方式实现。研究充实了城市公园绿地可达性评价案例,提出的基于手机信令数据和高斯两步移动搜索法的可达性分析方法不仅可应用于城市公园绿地布局与规划,也可为其他地理现象可达性分析提供思路参考。  相似文献   

The Role of the Important Agricultural Heritage Systems in the Construction of China’s National Park System and the Optimisation of the Protected Area System     

HE Siyuan  DING Lubin  MIN Qingwen 《资源与生态学报(英文版)》2021,12(4):444-452

Conservation-compatible development of rural communities is an important part of nature conservation objectives. Understanding the role of agriculture, which is often practiced in or bordering the protected areas in rural China, is critical for managing conservation networks considering that limited spatial areas are available for enclosed protected areas. Important Agricultural Heritage Systems stand out for their multi-functionality, and some of their values are compatible with nature conservation. This paper examined the concept, management objectives and resource management characteristics of the Important Agricultural Heritage Systems (IAHS) by analysing their interactions with national parks in terms of community development. The results reveal that management strategies of dynamic conservation, integrated protection and adaptive management of the IAHS can contribute to those national park management objectives concerning conservation-compatible livelihood. However, the typology of the protected area system, including the traditional agricultural system as a new type, needs further consideration.  相似文献   

Diversity of Plant Resources in Qunli National Urban Wetland Park in Harbin,China

Wetland parks play various ecological roles, including maintaining regional ecological balance, and connoting and compensating water sources. Taking Harbin Qunli National Urban Wetland Park as the research object, the diversity of plant resources in wetland parks is investigated and analyzed with the goal of providing a scientific basis for ecological restoration and the conservation and utilization of urban wetlands. Field survey, sampling and data collection methods were used to study the wetland plant resources and their life types (e.g., vines or shrubs), ecological types and distribution types. The study found 60 families, 129 genera and 160 species of wetland plants in Qunli National Urban Wetland Park, including 56 families, 123 genera and 151 species of angiosperms, which include 48 families, 101 genera and 127 species of dicotyledons and 8 families, 22 genera and 24 species of monocotyledons; 2 families, 2 genera and 3 species of ferns; and 2 families, 4 genera and 6 species of gymnosperms. The family composition is dominated by those families that included 10 or more species, and the dominant families are Compositae and Rosaceae. The genus composition is dominated by genera with four or more species present, and the dominant genera are Acer, Malus and Artemisia. Among the six life types, herbaceous plants are dominant, with a proportion of 62.50% of the species. The ecological types are divided into three categories: wet, mesophytic and aquatic plants, with wet plants accounting for the largest proportion, i.e., 56.25% of the total number of plant species. There are five distribution types of plant families and 10 types of the genera, with both families and genera dominated by the Northern Temperate types, so the flora has obvious temperate characteristics.  相似文献

主题公园周边土地利用动态变化及其驱动机制——以常州中华恐龙园为例   总被引：1，自引：0，他引：1  

汤傅佳  黄震方  陈晓艳 《地域研究与开发》2016,(5)

以常州中华恐龙园为研究对象,选取该处土地利用重要变化节点2000—2010年为研究时段,利用GIS/RS手段,从土地利用变化速度、土地利用扩展强度和土地利用转移方向等方面对中华恐龙园周边土地利用变化时空特征进行定量分析。结果显示:2000—2010年中华恐龙园周边10 km缓冲区内各种土地利用类型均有较大变化,随着缓冲区范围的扩大,其建设用地变化速率变缓,相比而言,2005—2010年间的变化强度和规模比2000—2005年间大。研究区内建设用地变化与中华恐龙园的发展水平呈显著相关。依托区域形象、人文环境、人口集聚等保障因素,在政府金融、财税、土地等政策的引导下和各项经济因素的推动下,主题公园周边的土地实现了功能转变、价值提升且土地利用方式朝着集约化的方向发展。  相似文献   

长江中游城市群石化产业空间组织研究——现状、机制与路径     

田超  王磊 《世界地理研究》2016,(3):106-114

石化产业是关乎国民经济的重要产业,在当前我国大规模发展石化产业的背景下,有必要对其空间组织进行深入讨论。基于长江中游城市群石化产业空间组织的分布状况,利用空间聚类、线性回归等数学工具,从其影响机制、问题评价和发展路径等方面进行分析,对长江中游城市群石化产业空间组织进行研究。结果表明长江中游城市群石化产业的空间集中程度不高,发展水平较低,需要通过培育和壮大产业集群来促进生产要素合理布局,提升产业竞争力,加速城市群建设。  相似文献
