摘要

[目的] 根据“耕地优先，兼顾园、林、草用地”的原则，进行烟台市农用土地适宜性评价，为烟台市土地合理利用提供理论依据。[方法] 以山东省烟台市为研究区域，以DEM数据为基础，运用ArcGIS的空间分析功能提取海拔高度、坡度、地表起伏度，结合有效土层厚度因子，确定最佳农用土地适宜性评价指标体系，生成耕地、园地、林草地的适宜性等级分布图，最终得到烟台市农用土地适宜等级的空间布局。[结果] 与烟台市第二次土地调查数据进行对比，烟台市目前的土地利用以耕地为主，占土地总面积的33%，大于适宜性耕地面积；实际园地面积小于适宜性面积；林草地的实际面积略小于适宜性面积。[结论] 烟台市土地利用存在一定的不合理性，具有一定的调整空间。

Abstract

[Objective] According to the principle of giving priority to cultivated land and secondarily considering garden

forest and grass land in land management

the suitability evaluation of the agricultural land was carried out to provide a theoretical basis for rational using of the lands of Yantai City.[Methods] Taking Yantai City of Shandong Province as the study area

using the function of ArcGIS spatial analysis to extract evaluation factors as altitude

slope

relief degree of land surface from DEM data. Combining with soil thickness investigation

the best suitability evaluation index system of agricultural land were determined. Upon which

the distributional suitability rank map of cultivated land

garden

forest and grass land was generated

and the spatial distribution of agricultural land suitability level of Yantai City was formed.[Results] In comparison with the data of second land survey of the Yantai City

the major area of land using was cultivated land

took up about 33% of the total land and covered more than the suitable area. Actual area of garden was smaller than the suitability area

and the actual forest and grass land area was a little less than the suitable area.[Conclusion] The land using of Yantai City is not reasonable

and has a certain room to be adjusted.
