1 main task:
The main task of ecological evaluation is to recognize the characteristics and functions of the ecological environment, to clarify the nature and extent of the impact of human activities on the ecological environment, and to specify the countermeasures and measures to be taken to maintain the functions of the ecological environment and the sustainable use of natural resources.
2 basic methods:
Currently, the ecological evaluation methods often used mainly include graphical superposition method, ecological mechanism analysis, analogy method, list list method, quality indicator method landscape ecology method, productivity evaluation method and mathematical evaluation method.
3 Significance:
Ecology is the basis of nature conservation, so to understand the significance and role of a protected area, its ecological evaluation is a very important thing, the ecological evaluation of a protected area, in fact, is the evaluation of each ecosystem therein, especially the ecosystem that plays a major role in the evaluation of the quality of the ecosystem itself, so the ecological evaluation itself is both an objective natural Therefore, ecological evaluation itself is not only an objective understanding of nature, but also involves the impact of human production and life. As we all know, the ecosystem is composed of organisms and the environment, therefore, to evaluate the ecosystem and the whole protected area, the first step is to evaluate the plant and animal species and ecological environment separately, and then to evaluate the ecosystem and the protected area as a whole, so that we can have an analytical and comprehensive understanding of the protected area.
