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 pattern of residential land recylcling in China's rural areas has changed into a simple cycle model,resulting in second abandonment after land consolidation and environmental pollution in some areas. Here we used ecological land as a new direction for rural residential land recycling under the ecological concept. We then built a recycling evaluation system with human-land multi-factors,and put forward a framework for evaluating the priority direction of residential land recycling to reduce idle cultivated land and improve the eco-environment. Using Fang County in Hubei as the empirical area, we establish cultivated land and forest land as examples of two priority rural residential recycling directions,and suggest the recycling of more than 400 pieces of rural residential land through a comparative study between the improved TOPSIS method and comprehensive scoring method. The result shows that potential reusable land has obvious regional characteristics and is mainly concentrated in towns with excellent or poor traffic location. However,the overall scale of potential land has been declining yearly,and the results of the two methods demonstrate that less than half(45.46% and 30.67%,respectively)of residential land is suitable for cultivation. The evaluation system is effective at a micro-level,and there is room to expand the dimensions of influencing factors and enrich the diversity of evaluation results. The recycling evaluation is particularly urgent and the diversity of evaluation methods makes it possible to flexibly determine the scale of reusable land,followed by the integration of the processes and indicators of various land consolidation projects. In the future study, we should focus on establishment of the evaluation framework through the whole process of residential land recycling, and take the factors influencing the recycling implementation into consideration.
