摘要
根据靖边县农用地分等定级资料,结合GIS软件分析土地利用基础数据,得到靖边县待整理耕地面积为100 209.9hm2,占总耕地面积的92.33%。在确定待整理耕地面积的基础上,靖边县被划分为3个农用地整治潜力分区,1级区和2级区可增加耕地面积为3 245.76hm2,3级区的整治工作一方面受制于自然条件,另一方面需要满足生态服务功能而受到限制。通过多因素综合指数法与GIS相结合的评价方法能够有效提高分区结果的合理性。农用地整治潜力分区结果可确定土地整治的重点方向,为靖边县土地整治政策的制定提供理论参考。
According to the classification and grading of farmland in Jingbian County of Shaanxi Province, the foun dation data in relation to land utilization were processed with GIS technology and the cultivated land area reserved in the county was found to be 100 209.9 hm2, accounting for 92.33G of the total cultivated land area. By ensuring the cultivated land area reserved, farmland in Jingbian County could be divided into three regions of consolidation potentiality. The areas of farmland consolidation potentials for the I and 11 level regions were roughly 3 245.76 hm2. In the HI level region, the farmland consolidation was not only restricted by the natu- ral conditions, but also restricted by the ecological service functions. It is more suitable for the classification of farmland consolidation potentiality using the comprehensive multiple indexes in combination with GIS technology. Results of the classification of farmland consolidation potentiality can be used to find the key direction of land consolidation, which helps the local authorities to make the policies of land consolidation.
