Problems solved by technology

However, the existing research has not involved the biodiversity change, community succession mechanism, spatial pattern of psammophyte dominant population and its response relationship with soil moisture spatiotemporal heterogeneity in alpine sandy land vegetation restoration under habitat stress conditions, etc. However, this is the premise and basis for comprehensive assessment of vegetation restoration potential in alpine valley sandy land

Embodiment Construction

[0055] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0056] see figure 1 , the embodiment of the present invention provides a method for assessing vegetation recovery potential in alpine sandy land, comprising the following steps:

[0057] Step S100, according to the habitat conditions of different types of sandy land in the alpine region, determine the vegetation restoration target;

[0058] Step S200, using the analytic hierarchy process to establish a hierarchical structure model for evaluating the restoration potential of different types of sandy land vegetation;

[0059] Step S300, using the hierarchical structure model for evaluating the restoration potential of the sandy land vegetation, constructing a judgment matrix, a single-level ranking list, and a total-level ranking list;

[0060] Step S400 , using the fuzzy comprehensive evaluation method to perform ...

Abstract

The invention discloses a high and cold sand land vegetation recovery potential estimation method. The method comprises the following steps that according to growth conditions of different types of sand land in high and cold areas, a vegetation recovery target of the high and cold areas is determined; a hierarchical structure model of vegetation recovery potential estimation of the different types of sand land is built by using an analytic hierarchy process; a judgment matrix, a hierarchical single-row sequence table and a hierarchical total-row sequence table are built by means of the hierarchical structure model of vegetation recovery potential estimation of the sand land; comprehensive evaluation calculation is conducted on the vegetation recovery potential of the different types of sand land by means of a fuzzy comprehensive evaluation method. According to the high and cold sand land vegetation recovery potential estimation method, the good and bad degree comprising 15 evaluation factors and total evaluation of the vegetation recovery potential can be respectively output, and a scientific decision support method can be provided for making of a vegetation recovery policy of the different types of high and cold sand land in different areas of the Qinghai-Tibet Plateau.

Description

technical field [0001] The invention relates to the technical field of ecological protection and restoration, in particular to a method for evaluating the restoration potential of alpine sandy land vegetation. Background technique [0002] Carrying out vegetation restoration potential assessment is the basis for ecological restoration practice on difficult sites (degraded sandy land and engineering disturbance areas). When faced with a degraded ecosystem, the first consideration is to determine its restoration to a certain target ecosystem. Capacity, that is, assessing the size of the recovery potential. The United States Natural Resources Council (UNRC), Cairns and Peng Shaolin emphasized that restoration is to restore the damaged ecosystem to the ideal state before the disturbance. However, due to the lack of understanding of the historical evolution of the ecosystem, the restoration time is too long, the cost is too high and other practical constraints, this ideal state ...
