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.
