摘要： 本文以土地类型生态属性为依据, 以黄土高原正宁县为案例区, 开展土地生态适宜性与生态系统耦合关系研究。研究结果表明, 土地类型与生态系统间有良好耦合关系, 是进行土地生态评价, 构建区域合理生态系统结构的主要依据。文章最后以构建正宁县土地合理生态系统结构与发挥生态综合功能为目标, 提出了该县生态建设战略和对策措施, 对指导黄土高原地区生态建设具有普遍意义。

Abstract: Based on ecological characteristics of land types, and by using Zhengning County, Gansu Province locatedon the Loess Plateau as a study area, the coupled relation between ecological suitability and ecological system of land types was studied. The research indicated that there is a satisfactory coupled relation between landtypes and ecological systems, which provides the main basis for land ecological evaluation and construction ofrational ecological system structure. With restructuring rational ecological system and increasing comprehensive ecological functions in Zhengning County as their objectives, the authors proposed ecological construction strategies and measures for the county, which is also helpful to the ecological construction on the Loess Plateau.

Key words: ecological functions, ecological system structure, land type, Zhengning County of Gansu Province
