Embodiment Construction

[0036] The following examples are used to illustrate the present invention, but are not intended to limit the scope of use of the present invention.

[0037] We chose the wetland vegetation of Nansi Lake as a case of restoration species screening, and evaluated the candidate species step by step.

[0038] Located at the junction of the North China Plain and the Huanghuai Plain, Nansi Lake is the largest freshwater lake in the eastern plains of northern my country. It is not only an important water source in Shandong Province, but also the largest inland wetland. Nansi Lake is composed of four connected lakes, Nanyang Lake, Dushan Lake, Zhaoyang Lake and Weishan Lake from north to south. Nansi Lake is a regulation and storage lake for the South-to-North Water Diversion Project. There are 15 main rivers that directly discharge into Nansi Lake. The East Route of the South-to-North Water Diversion Project will be officially put into operation in 2013. At that time, the water qual...

Abstract

The invention method relates to a method for sieving vegetation recovery species, and belongs to the technical field of biological recovery. According to the method, an index system for sieving the recovery species of wetlands is established, the grading standard and weight of each index are determined, and attribute data of alternative species obtained by the conventional ecological analytical method and literature survey analytical method is graded comprehensively to sieve the recovery species of the wetlands aiming at different sites and recovery targets. The invention provides a special easy, scientific and objective comprehensive evaluation method for sieving the recovery species of the wetlands.

Description

technical field [0001] The invention relates to a species screening method for wetland vegetation restoration, which belongs to the technical field of ecological restoration. Background technique [0002] Wetland is an important ecosystem on the earth. It has many reputations such as "kidney of the earth", "biological gene pool", and "cradle of human beings". However, due to years of over-exploitation and even destruction by humans, the wetland ecosystem is facing serious degradation and urgently needs to be restored. Wetland vegetation is the basis of wetland biodiversity and the hub of material circulation and energy flow in wetland ecosystems. Through its special ecological characteristics, it can sensitively reflect the characteristics of the wetland environment and promote the formation and development of the wetland itself. It maintains the normal operation of wetland ecosystem structure and function. Therefore, the primary task of wetland restoration is wetland vege...
