川西安宁河流域生态地质环境动态演化分析

本文通过调查，结合大量前人资料和多时段的遥感解译成果，在研究人类活动影响下地质环境与生态系统间相互作用关系的基础上，进行了生态环境演化的动态演变分析，并选择具有代表性的3个典型地段进行深入剖析，充分揭示了人类活动-生态系统-地质环境三者之间相互作用规律，初步建立了流域生态地质环境演化机制概念模型。为改善、恢复和保护生态地质环境，实现人与生态地质环境的协调，促进区域经济的可持续发展提供科学依据。

An analysis of dynamic evolution of the eco-geological environment in the Anninghe River watershed in western Sichuan Province

It is necessary to construct an ecological barrier and preserve the ecological environment in the upper reach of the Yangtze River in the development of the western China. By conducting a two-year investigation of current eco-geological environment of the Anninghe River watershed, analyzing the previous available data and identifying the remote sensing images, the dynamic evolution of the ecological environment of three representative regions are examined. The interactions among human activities, the ecological system and the geological environment have been revealed and a conceptual model of the evolution of the eco-geological environment in the watershed has also been established. The research results will be provided as a scientific basis for improving and recovering the eco-geological environment, adjusting the human being and the eco-geological environment and promoting the sustainable development of the economy of the region.
