【摘要】 在实地调查采样和测试分析基础上,利用主成分和相关分析模型筛选建立区域绿色蔬菜地适宜性评价主导因子体系,借助GIS和动态聚类分析模型评价区域耕地对绿色蔬菜生产的适宜数量、质量及其分布。结果表明坡度、质地、耕层厚度、灌溉条件和环境污染综合指数等20个因子可作为区域绿色蔬菜地适宜性评价的主导因子。荔城区适宜发展绿色蔬菜生产的耕地面积5014.22hm2,占基本农田保护区耕地总面积的55.72%,主要分布于北高和新度镇,合计占全区绿色蔬菜地总面积的67.06%,全区绿色蔬菜地的总体质量不高,中度和一般适宜的二、三等地面积合计占全区绿色蔬菜地总面积的66.85%,其中黄石和新度镇的绿色蔬菜地质量相对较高,而西天尾和北高镇的绿色蔬菜地质量则较差。更多还原

【Abstract】 Base on field investigation, sampling and analysis, the major factor system to evaluate the suitability of regional green vegetable field was selected and established by the models of pricipal component and correlation analysis, and the quantity, quality and distribution of regional cropland suited for green vegetable production were evaluated by GIS integrated with dynamic cluster analysis model. The results showed that 20 factors, including slope, texture, thickness of ploughing layer, irrigation condition and multiple index of environmental pollution etc., could be used as major factors to evaluate the suitability of regional green vegetable field. The total areas of green vegetable field in Licheng were 5014.22 hm2, which was 55.72 % of basic farmland conservation area. The green vegetable fields were mainly distributed in Beigao and Xindu, which were 67.06 % of the total in Licheng. The overall quality of green vegetable field in Licheng was lower, the areas of the second and third grade green vegetable field were 66.85 % of the total in Licheng. The qualities of green vegetable fields in both Huangshi and Xindu located in plain area were higher and those in both Xitianwei and Beigao were lower.更多还原
