Abstract:

The authors systematically identify and classify land use functions based on the system theory, and then construct the multi-scale and multi-level evaluation index system of land use functions from three aspects of economy, society and ecology from the perspective of patch scale. A preliminary attempt is made to obtain and spatialize index data. The results show that land use functions has multiple levels and regional characteristics, corresponding classification and evaluation index system should be established according to different regional background and research scale. Land use functions are related to land use structures, and its evaluation scale is extended to the micro-scale, which is helpful to expand the scope and enrich content of the study of land use functions.

Key words: land use functions, system theory, classification and evaluation, index system, multi-scale

摘要：

基于系统论中要素–结构–功能原理, 对土地利用系统多功能进行系统识别和分类, 建立土地利用多功能分类体系; 从经济–社会–生态维度构建多尺度、多层次的土地利用多功能评价指标体系, 并对指标数据的获取和空间化方法进行初步探讨。结果表明, 土地利用多功能具有多层次性和区域性, 应针对不同的区域背景和研究尺度建立相应的分类与评价指标体系。将土地利用功能与土地利用结构相联系, 并将评价尺度延伸至地块这一微观尺度, 拓展和丰富了土地利用多功能研究的范围与内容, 为土地利用多功能研究提供新的思路和途径。
