黄土山丘区农村居民点整治优先度分析

Evaluation ofrural residential land consolidation priority in the Loess Hills area

农村居民点整治工作对于保障我国粮食安全、建设用地需求及实现耕地总量动态平衡具有重大意义,同时整治工作的开展对于土地利用效率的提高也具有十分重要的作用。全文以黄土山丘区中的47个村为研究单元,以自然和社会经济为准则层共选取了15个指标,分别用层次分析法和熵权法求权重,将计算所得权重加权平均作为指标权重值,并利用综合评价法对农村居民点整治的综合值进行计算,最后运用聚类分析法根据研究区农村居民点综合评价分值将研究区划分为4个整治优先度分区,结果表明,研究区农村居民点整治的空间差异较大,一级优先整治区包含有8个村,占整个全区总面积的17.7%,该地区主要自然环境较差,居民点占地面积较多,但同时经济状况良好,应优先整治;二级优先整治区包含有7个村,占全区总面积的15.91%。该地区所处地理位置相对较好,人口密度较低,整治潜力较大,但村庄整体经济水平相较一级整治区要差,整治的难度高于一级整治区;三级优先整治区包含有13个村,约占全区总面积的32.29%,该地区所处自然环境较好,采煤损毁状况轻,整治潜力不大;四级优先整治区:整治区包含19个村,约占全区总面积的32.51%。四级优先整治区居民点人口密度较高,交通便利,且几乎没有采煤损毁区域,整体状况较好,整治潜力较小。整治工作的开展不仅要考虑整治模式和整治手段,科学的整治顺序能使整治工作的开展收到事半功倍的效果。整治优先度的先后顺序取决于村庄所处自然环境及社会环境的危险性以及当地的经济发展水平,其中前者决定了整治工作开展的迫切程度,而后者则决定了整治工作开展的难度大小。

Rural residential renovation has great significance for the food safety,construction land demand,realizing the dynamic balance of the total arable land and improving land use efficiency.In the paper,47 villages in the Loess Hilly Region was made as the research unit and 15 indicators were selected in the natural and social economy aspect as the criterion layer.AHP and entropy method was used to calculate the weight respectively,whose calculated weight average value was made as the final index weight.The comprehensive value is calculated and by the comprehensive evaluation method,which was finally divided into 4 remediation priority partition using cluster analysis.According to the results,it showed that the spatial difference of rural residential consolidation was evident.The priority one remediation area contains8 villages,accounted for17.7%of the total area of the region,which have poorly natural environment,large residential area and good economic situation on the contrary,for which should be remediated first.The priority two remediation area contains 7 villages,accounted for 15.91% of the total area.In the area,the geographical position was relatively good.It owned low population density,large remediation potential,but poor economic level,which increased the difficulty in renovation.The priority three remediation area contains 13 villages,accounting for about 32.29% of the total area.It was a area consist of a good natural environment with light coal mining damage,which had little renovation potent.The priority four remediation area included 19 villages,accounted for about 32.51% of the total area.This area was a place where the population density was higher,the transportation was convenient,and almost no coal mining damage areas,the overall situation of which was better,and the remediation potential was small.The development of the regulation work should not only take into consideration the mode of regulation and the means of regulation,but also the order of scientific rectification,so that the work of regulation can be carried out with twice the result with half the effort.Regulation of priority order depends on the village where the natural environment and social environment risk and the level of local economic development,of which the former determines the urgency of the renovation,and the latter determines the difficulty of the renovation work carried out.
