区域生态系统的演化模式分析

Analysis on Evolution Pattern of Regional Ecosystem

区域生态系统以人的行为为主导、以自然环境为依托、以资源流动为命脉、以社会经济体制为调节器,其整体演化过程呈现为S形曲线,有持续发展、波动发展和衰退三种演化模式。认识的目的在于因势利导,主动调控,正确决策,引导区域生态系统不断地向更高层次演化。

We view human behavior as leading, natural environment as reliance, resource flow as lifeline and socioeconomic system as regulator in regional ecosystem whose whole process of evolution presents the curve of shape S and includes three patterns such as sustainable development, fluctuant development and decay. This paper aims to guide regional ecosystem to higher level of evolution continuously by improving the occasion, active regulation and proper decision.
