基于多元数据融合的土地生态指数构建--以金坛市为例

摘要

Taking Jintan city as an object of empirical study , this article firstly selected some indexes according to the regional characteristics of this city , secondly determined the data sources , calculation methods , standardized functions and weights , and fi-nally got the land ecological indexes in administrative village scale .The regularity of land ecological index distribution showed that the land ecological quality of the east part of Jintan city was higher than that of the west part .The centre-oriented annular changing trend of land ecological index in Jintan city roughly conformed to the law of urban -rural gradient .%以金坛市为研究对象，根据该市区域特点选取指标、确定数据来源和计算方法、进行标准化函数及权重确定，得到了金坛市行政村尺度的土地生态指数。分布规律表明金坛市土地生态质量东部高于西部，以金坛主城区为中心向四周递增的圈层状发展趋势大致符合城乡梯度规律。
