摘要： 摘要：本研究旨在通过比较现状与适宜性评价结果，对庄河市农业土地利用空间结构及农业布局进行分析。本研究进行庄河市农业土地资源适宜性评价的具体做法是：首先，根据选择评价因子的原则确定了用于庄河市农业土地资源适宜性评价的7个评价因素。其次，分别就这7个评价因子做庄河市农业土地适宜性单因子评价分析。再次，应用层次分析法确定了各因子的权重，采用综合制图单元为评价单元。然后，利用土壤质地、灌溉保证、交通状况等7个评价因子的图形资料和有关数据资料分别建立了各因子的空间和属性数据库，利用地理信息系统软件进行叠加分析，生成农业土地适宜性评价图，得到庄河市宜耕地、宜林地、宜牧地及其各分等的数量与空间分布。农业土地适宜性评价结果表明，庄河市宜耕、宜林、宜牧地面积分别为：1369.34km2，1639.91km2，764.75km2；分别占土地总面积的36.28%、43.45%、20.26%。

Abstract: Abstract:Comparing present situation and the result of the suitability evaluation, the spacial adjustment of land use structure and agricultural overall arrangement of Zhuanghe town has been analyzed. The rational advices have been put forward on agricultural overall arrangement in the future on the basis of analyzing the obstacle factor of land use in Zhuanghe areas. It is that this research carries out the specific practice of agricultural land resource suitability evaluation: First, according to the principle of selecting the evaluated factors, the 7 evaluation factors used in the land resource suitability evaluation have been defined. Secondly, each of the 7 factors is evaluated based on principles of the agricultural land suitability evaluation in Zhuanghe area. Thirdly, the weight of each factor has been calculated by the measure of Analytic Hierarchy Process and the unit of the land suitability evaluation application has been determined with compositive cartography. Then, the spacial database of each factor has been established using the relevant data information and the graph information of 7 evaluation factors such as soil texture, irrigation guarantee and traffic status and so on. The result of the agricultural land suitability evaluation would be obtained after the overlaying analysis by using GIS software. Then we get the classified quantity and space distribution of the agricultural land that is suitable for plantation, forest and herd of Zhuanghe town agricultural land resources. The agricultural land suitability evaluation result shows that the area of the land suitable plantation, forestry and herd of Zhuanghe town is 1369.34km2，1639.91km2 and 764.75km2, and take 36.28%,43.45% and the 20.26% of land gross area respectively.
