摘要
为了探讨土地资源评价的方法,1987-1988年对余庆号小流域土地资源状况进行了系统的调查、分析与评价。对流域内生物、土壤、地文因素及其有关项目进行了分析与筛选,确定了评价的原则及标准。对模糊综合评判的数学原理及方法进行了探讨。编绘了1/10000土地评价图。提出了不同等级土地的分布、数量、适宜性以及土地开发、利用方向。
A program was conducted in 1987-1988 so as to survey, to analysis, and to evaluate the land resourses of Yuqinghao River Basin in Gongzhu ling, Jilin. Biological factors, soils, landscape and some other items were studied and selected. Meanwhile, the principles and criteria for land resourses evaluation were determined and the combnined fuzzy evaluation method was discussed. A land resourses map (scale l/l0000)was composed.
