摘要
土地生态经济系统具有基质的自然生态系统性、运行方式的人类技术系统性、运行目标的社会经济系统性等特点;土地生态经济系统运行的压力来源于人类生存和发展的需要,其状态可以从量态组合、质态组合和空间组合三个方面进行描述,并在自然生态和社会经济方面得到响应。在此基础上构建土地生态经济分区的基质(B)-压力(P)-状态(S)-响应(R)模型,利用所建立的指标体系和系统聚类法进行土地生态经济分区,分区结果比较符合当地的实际情况。
Land eco-economical system is a kind of complicated system. Its base material, working way and acting target respectively has the characteristics of ecosystem,human being technology system, and social-economic system. The pressure of land eco-economical system originates from the existence and development of human beings, the state of which can be described from three aspects： the structure of quantity, the structure of quality and the structure of space. The respouse of land eco-economical system can be represented in the field of natural-ecology and social-economy. Therefore, this paper builds an model of land eco-economical regionalization based on base （B）- pressure （P） - state （S）- response （R）, and makes use of the index system and method of system clustering to carry out land eco-economical mgionalization in a city of Hubei Province. The result accords with the local reality.
