Embodiment Construction

[0011] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and specific conditions.

[0012] Depend on figure 1 , 2 Shown, the present invention is realized by the following steps:

[0013] (1) According to the river degradation situation, formulate the restoration target of the river ecosystem, the method is:

[0014] Collect data on the landform, riparian zone characteristics, hydrology, water quality, aquatic organisms and landscape characteristics of the river before restoration, and understand the degradation status of the damaged river ecosystem before the restoration of the river ecosystem;

[0015] According to the degradation status of the damaged river ecosystem, formulate the restoration goals of the river ecosystem in terms of landform, hydrology and water quality, aquatic organisms and river functions. The establishment of restoration goals reflects the social needs, economic suppor...

Abstract

The invention relates to an evaluation method for a river ecological restoration effect. With the method, a problem of evaluation of a river ecological restoration effect to realize environment protection can be solved. According to the technical scheme, a restoration target of a river ecological system is set based on a river deterioration situation; a water ecological restoration effect evaluation indicator hierarchical structure model is constructed by using a frequency statistics method and a theoretical analysis method; weights of evaluation indicators are determined by using a group decision analytic hierarchy process; grading and standardization processing is carried out on the indexes of the evaluation indicators; an evaluation criterion of the river ecological restoration effect is formulated; and evaluation of a river restoration effect is carried out based on the evaluation indicators of the river restoration effect. The provided method is novel and unique and can be operated and used easily; and the effect is good. On the basis of evaluation of the restoration effect of the river, river control and ecological restoration can be guided; environmental protection can be realized; and the great economic and social benefits can be created.

Description

technical field [0001] The invention relates to river ecological protection, in particular to a river ecological restoration effect evaluation method. Background technique [0002] With the rapid development of industrial civilization, human demand for water resources has increased greatly, resulting in a shortage of water resources; in addition, the discharge of a large number of pollutants, the artificial transformation of river channels, and the destruction of riverside buffer zones have seriously affected river ecology. function, resulting in the ecological degradation of the river, and the degradation of the ecosystem has become one of the serious problems facing the world. Ecological restoration is to take the currently degraded ecosystem as an object, and on the basis of diagnosing the damage mechanism, restore its function and structure, and finally make it reach a self-sustaining state. Ecological restoration provides new ideas and opportunities for river resource ...
