【摘要】：黄土高原地区总体用地适宜性较差,土地资源紧缺。受自然条件及社会发展等的影响,该地区的农村建设用地的利用呈现出粗放、效率低的特点。近些年,又有空心村、土地撂荒等新问题出现。通过农村建设用地整理来提高农村土地的利用效率、解决农村土地利用的新问题、增加用地给就显得十分重要,尤其是在土地资源紧缺的黄土丘陵区。而要使土地整理顺利进行,农村建设用地整理潜力评价就必不可少。本研究以志丹县为例,进行黄土高原地区的农村建设用地整理潜力的评价。结合土地集约理论、系统工程论等相关知识,运用GIS技术及数理统计方法,从潜力水平和空间分布两个方面对农村建设用地整理潜力进行定量评价。首先在已有数据的基础上构建地理数据库,依托数据库,利用人均建设用地标准法评价模型,实现研究区理论潜力的评价。评价结果表明研究区理论潜力大,空间分布有差异。其次基于地区的现实环境,构建潜力修正指标体系,利用多因素综合评价模型,进行理论潜力修正,测算实际潜力。实际潜力评价结果表明,各单元的实际条件对潜力实现的影响差异大,整理潜力评价有必要考虑现实因素的影响,且各单元经济社会发展越好越利于整理潜力的释放。在现实潜力评价的基础上,利用GIS技术的自然间断点分级法,以综合潜力系数为标准对研究区进行整理潜力分级。依据整理潜力评价结果,通过构建分区综合指标体系,利用综合叠图法进行整理潜力分区。最后分析评价结果对研究区农村建设用地整理提出实施建议。总体上,整个评价过程也表明GIS技术用于农村建设用地整理潜力的评价具有良好的适应性。
[Abstract]:The overall suitability of land use in the Loess Plateau is poor, and land resources are scarce. Under the influence of natural conditions and social development, the utilization of rural construction land in this area is characterized by extensive and low efficiency. In recent years, there are hollow villages, abandoned land and other new problems appear. It is very important to improve the efficiency of rural land use and solve the new problem of rural land use through the arrangement of rural construction land, especially in the loess hilly area where land resources are scarce. In order to make land consolidation smooth, rural construction land consolidation potential evaluation is essential. This study takes Zhidan County as an example to evaluate the potential of rural construction land consolidation in the Loess Plateau. Combined with land intensive theory, system engineering theory and other related knowledge, using GIS technology and mathematical statistics method, the potential of rural construction land consolidation is quantitatively evaluated from two aspects: potential level and spatial distribution. Firstly, based on the existing data, the geographic database is constructed, and the evaluation model of per capita construction land standard method is used to realize the evaluation of the theoretical potential of the research area by relying on the database. The evaluation results show that the theoretical potential of the study area is great and the spatial distribution is different. Secondly, based on the real environment of the region, the potential correction index system is constructed, and the theoretical potential correction is carried out by using the multi-factor comprehensive evaluation model, and the actual potential is calculated. The actual potential evaluation results show that the actual conditions of each unit have great influence on the realization of potential. It is necessary to consider the impact of practical factors on the consolidation potential evaluation, and the better the economic and social development of each unit is, the more conducive to the release of the consolidation potential. Based on the evaluation of practical potential, the natural discontinuous point classification method of GIS technique is used to classify the potential of the study area according to the comprehensive potential coefficient. According to the evaluation results of collation potential, a comprehensive index system was constructed, and the method of stacking map was used to sort out potential zoning. Finally, analysis and evaluation of the results of the study area of rural construction land consolidation proposed implementation recommendations. As a whole, the whole evaluation process also shows that GIS technology has good adaptability in evaluating the potential of rural construction land consolidation.
