三峡库区山地生态系统预警

Warning on Mountain Complex Ecosystem in the Three Goprges Reservoir Area

论述了三峡库区山地生态系统的特征 ,建立山地生态系统预警评价的指标体系和预警模式 ,在假定不作重大投资进行调控修复的前提下对三峡库区山地生态系统进行预警分析 ,复合生态系统及各子系统都将处于逆向演替状态 ,绝大多数子系统及复合生态系统在 2 0 10年前将处于各种预警状态。在预警分析基础上 ,提出优化调控战略要点 ,其核心是经济。

Authors expound the characters on the mountain complex ecosystem in the Three Gorges Reservoir(TGR) Area, set up the index system and the mathematical models of warning evaluation, and make the forecasting and warning on eco environment in the condition that do not invest much money to adjust and restore the mountain complex ecosystem in TGR Area. The complex ecosystem and its subecosystems will be the process of the negative evolution, the most of subecosystems and the complex ecosystem will be the status of the different warnings. Based on the warning on the mountain complex ecosystem in the TGR Area, authors put forward the adjusting strategies, the key strategy is the harmony between the social and economic development and the eco environmental construction.
