地质环境与生态环境雏论

生态环境是地质环境的“屏障”,对地质环境起着保护作用。当生态环境的森林植被遭受破坏或大气降水与气候条件发生变化时,将导致水土流失、地质灾害、土壤退化等一系列地质环境问题。另一方面,地质环境是生态环境的“载体”,对生态环境起着一定的控制作用。成土基岩是除自然地理气候条件外控制森林植被种属与空间分布的最重要因素。地质体特征与水文环境、地质背景与社会经济状况之间均存在着一定的依从联系。生态环境和地质环境是环境体系中的两个方面。生态环境的恶化将导致地质环境的脆弱,地质环境的自然属性控制着生态环境的基本状况。

A DISCUSSION ON GEOLOGICAL ENVIRONMENT AND ECOLOGICAL ENVIRONMENT

Ecological environment is the protecting "shield" for Geological environment. Ecological environment change, such as the destructions of forest vegetation, or changes in climate or atmospheric precipitation, will induce happening of a series of events of geological environment, such as soil erosion, geological hazards and soil degradation. On the other hand, geological environment is the "bearer" for ecological environment. Geological environment is closely concerned with the hydrological environment, which is important to the social economic development. Ecological environment and geological environment are the two aspects of environmental system. The deterioration of ecological environment will lead to the vulnerability of geological environment, while the natural attributes of geological environment shape the general scenario of ecological environment.
