【摘要】：低丘缓坡土地资源的开发利用,既能促进土地的集约利用,又能在一定程度上解决建设用地的供给瓶颈.该研究从自然因素、社会经济因素等角度出发,选取10个评价指标,借助GIS空间分析技术和多因素综合评价模型对四川省泸州市龙马潭区低丘缓坡土地资源的建设用地适宜性进行评价,并将评价结果划分为适宜、比较适宜、勉强适宜和不适宜建设4个等级.评价结果表明龙马潭区现有低丘缓坡土地资源18 552.51 hm~2,占该区土地总面积的55.69%;其中适宜建设的低丘缓坡土地资源主要分布在龙马潭区南面的极少部分区域,占龙马潭区适宜、比较适宜和勉强适宜建设的低丘缓坡土地资源总面积的32.43%;比较适宜的区域主要分布在宜建区域的周边地区,所占面积比例为50.30%;勉强适宜区域则零散分布在中部区域、与泸县接壤的西部区域以及与江阳区接壤的东南区域,所占面积比例为17.27%,其余部分均为不适宜区域.该评价结果可为龙马潭区低丘缓坡土地资源作为建设用地的潜在资源进行开发提供科学合理的参考依据.
[Abstract]:The exploitation and utilization of land resources on low hill and gentle slope can not only promote the intensive utilization of land, but also solve the bottleneck of supply of construction land to a certain extent. This study selects 10 evaluation indexes from the perspectives of natural factors, social and economic factors, etc. With the help of GIS spatial analysis technology and multi-factor comprehensive evaluation model, the suitability of construction land for low hill and gentle slope land resources in Longmatan District, Luzhou City, Sichuan Province is evaluated, and the evaluation results are classified as appropriate and more appropriate. The evaluation results show that there are 18 552.51 hmm2 of low hill gentle slope land resources in Longmatan district, accounting for 55.69g of the total land area in this area, among which the suitable low hill slope land resources are mainly distributed in Longma area. A very small part of the south side of the pool area, In Longmatan area, 32.43% of the total area of land resources of low hill gentle slope is suitable for construction, and the more suitable area is mainly located in the surrounding area of suitable construction area. The proportion of the area occupied is 50.30, and the suitable area is scattered in the central region, the western region bordering Luxian County and the southeast region bordering Jiangyang District. The results can provide scientific and reasonable reference basis for the development of low hill slope land resources as potential resources of construction land in Longmatan district.
