Embodiment 1

[0043] According to the steps of the present invention, the ecological service function of the Olympic Park water landscape ecological engineering is measured, specifically comprising the following steps:

[0044] (1) Use big data technology to comprehensively search for indicators related to landscape ecological engineering, construct an evaluation index system for ecological service functions of water landscape ecological engineering, and then obtain various evaluation indicators, which include water resources, water quality improvement, water conservation, rainwater Regulation and storage, absorption of pollutants, dust retention, noise reduction, microclimate adjustment, reduction of soil fertility loss, reduction of total soil erosion, biodiversity, carbon sequestration, tourism and entertainment, water landscape functions, and water culture inheritance.

[0045] (2) Assign values ​​to each evaluation index to obtain the index value of each evaluation index;

[0046] (3) ...

Abstract

The invention relates to the technical field of ecological service functions, particularly to a water landscape ecological project ecological service function test method and evaluation method. Specifically, an ecological service function evaluation index system is established, a normalized value of each evaluation index is obtained, a hierarchical structure model is established according to the evaluation index system, the weight of each evaluation index is obtained, an evaluation value zi of each service function in a criterion layer is obtained by using the formula zi=yi1 r1+yi2 r2+......+yij rj, and then a comprehensive evaluation value P of the water landscape ecological project ecological service function is obtained by using the formula P=z1 r1+z2 r2+......+ zi ri. The methods provided by the invention can achieve accurate and efficient evaluation of the water landscape ecological project ecological service function.

Description

technical field [0001] The invention relates to the technical field of ecological service function evaluation, in particular to a method for measuring and evaluating the ecological service function of water landscape ecological engineering. Background technique [0002] In recent years, with the development of urban greening, more and more water landscape ecological projects have been applied to greening projects, which not only have good landscape effects, but also can achieve certain ecological service functions. [0003] The ecological service function of water landscape ecological engineering refers to the comprehensive effect of various measures adopted in the construction of water landscape ecological engineering to maintain, improve and protect the natural environmental conditions on which human beings and human society depend. Its main functions are: to maintain and improving soil, protecting and conserving water sources, windbreak and sand fixation, carbon fixation ...
