引入生态理念的农村居民点再利用研究

【摘要】：中国农村地区现行的居民点再利用模式单一,部分地区出现复垦地二次抛荒的问题,与此同时,农村环境污染问题依旧严峻。本研究通过引入生态理念,将生态用地作为居民点再利用新方向,建立考虑人地多因素的再利用评价体系,得出再利用优先方向,以期减少耕地闲置、改善生态环境,并以湖北省房县为研究区,以耕地和林地为例,通过改进型TOPSIS法和综合打分法对比研究,给出该地400余块农村居民点土地再利用建议。结果表明:房县潜在可再利用居民点具有明显区位特征,土地总体规模不断下降;过半居民点地块被评价为"非耕"类型,不同评价方法下"宜耕"地块规模差异显著。研究指出:评价体系适合微观层面地块宜耕性的判别,有继续扩展影响因子维度、丰富评价结果多样性的空间;过去"复垦优先"模式不合理,再利用评价显得迫在眉睫,可结合实际需要选择不同方法设置各类土地规模,尝试融合各类土地整理项目的流程与指标;下一步需考虑居民点再利用实施中的影响因素,建立贯穿再利用全过程的框架体系。
[Abstract]:The current mode of reuse of residential areas in rural areas of China is single, and some areas have the problem of reclaimed land being abandoned again. At the same time, the problem of environmental pollution in rural areas is still severe. By introducing the ecological concept and taking ecological land as a new direction of residential land reuse, this study establishes a reutilization evaluation system considering human and land factors, and obtains the priority direction of reuse, in order to reduce the idle cultivated land and improve the ecological environment. Taking Fangxian County of Hubei Province as the study area, taking cultivated land and woodland as an example, through the comparative study of the improved TOPSIS method and the comprehensive scoring method, some suggestions for land reuse of more than 400 rural residential areas in this area are put forward. The results show that the potential reusable settlements in Fangxian County have obvious location characteristics, and the total land size is decreasing, and more than half of the residential areas are evaluated as "non-tillage" type, and there is a significant difference in the scale of "suitable tillage" plots under different evaluation methods. It is pointed out that the evaluation system is suitable for judging the suitability of land plots at the micro-level and has the space to expand the dimension of influence factors and enrich the diversity of evaluation results. In the past, the mode of "reclamation priority" is unreasonable, and the reuse evaluation is urgent. We can choose different methods to set up all kinds of land scale combined with the actual needs, and try to integrate the processes and indicators of various land consolidation projects. The next step is to consider the influencing factors in the implementation of residential reuse, and to establish a framework system that runs through the whole process of reuse.
