收集了徐州市睢宁县的空间数据,并运用了 Arcgis 软件对数据进 行了专业提取并进行了系统的分析,同时选取了各类土地转化为耕地负成本、海 拔、坡度、与农田水利设施距离四个评价

摘要耕地是与我国民生息息相关的重要资源。我国虽然土地面积辽阔,人均占有 量却十分地低,远远低于世界的平均水平,社会经济快速地发展,导致了人们需 要更多的土地来满足自身的需求,但是由此产生的问题也是日趋增多,突出表现 在建设用地增加速度过快,后备资源匮乏且利用方式不够好,因此需要占用大面 积耕地,其中包括高等质量用地,这项举措都没有从根本上解决问题。现如今越 来越多的人开始关注如何科学合理地利用土地。72228

本文大量收集了徐州市睢宁县的空间数据,并运用了 Arcgis 软件对数据进 行了专业提取并进行了系统的分析,同时选取了各类土地转化为耕地负成本、海 拔、坡度、与农田水利设施距离四个评价因子,还建了一个评价体系,采用叠加 分析法得到最终的适宜性耕地分布图、不同适宜程度土地的面积以及比例,最终 得到了睢宁县耕地空间适宜性评价结果。从结果人们可以较为准确地了解到睢宁 县土地质量状况以及分布情况,并将分析结果进行运用,为今后相关部门可以制 定出具体有效的措施提供了依据。

Study on the Suitability Evaluation of Cultivated Land in Suining County

Abstract Cultivated land is an important resource which is really related to the people's everyday life。 Although our country land area is broad , The fast economic development of society has led to people need more land to meet the needs of their

own。 But the resulting problem is also increasing。 The problem is Construction land increasing too fast, lack of reserve resources and the using way is not good enough, so you need to occupy large area of cultivated land, including land  for higher quality。 This move did not fundamentally solve the problem。 Nowadays more and  more people began to focus on how scientific and rational use of land。

This paper takes Suining County of Xuzhou city as the study area, it is on the basis of GIS data extraction and analysis the space projects and selecting land classification, altitude, slope and negative cost of farmland water  conservancy facilities from four evaluation factors, builting a evaluation system, using the method of superposition is eventually the suitability of the area of cultivated land distribution and different level land and proportion。 Finally, the results of Spatial Suitability Evaluation of cultivated land in Suining county are obtained。 From the analysis results that people can more accurately understand the Suining county land quality condition and distribution, and the results of the analysis of reasonable use for the relevant departments to develop a specific and effective measures to provide the basis。
