Embodiment 1

[0014] Example 1: Comparing the evaluation results of the traditional ecological suitability assessment and the ecological suitability assessment of hydropower development considering the water footprint in the case area

[0015] Select the key factors that have the greatest impact on regional hydropower development and construction as ecological impact factors. Expert judgment was used to conduct decision-making analysis, and representative indicators were determined as influencing factors for regional ecological suitability judgment (Table 1). In addition, in order to ensure the healthy development of ecological protection areas, ecologically sensitive areas are taken as limiting factors. The weight of each factor is determined by the analytic hierarchy process, and the ecological suitability evaluation model of hydropower development in the basin is constructed. The water footprint related indicators in the index system are per capita water footprint, water footprint land d...

Abstract

The invention discloses a hydroelectric development ecological suitability evaluation method with water footprint taken into consideration. The particularity of a hydroelectric development project are comprehensively considered, a water footprint index is introduced and combined with an original social and economic index, and a traditional ecological suitability evaluation index system is improved. The method overcomes the defects that the relation between water resource utilization and human consumption activities is not taken into consideration in a traditional evaluation method, the human consumption activities are reflected through the water footprint, and the relation between the water footprint and the human consumption activities is established; compared with the traditional ecological suitability evaluation method, the method has the advantages that an evaluation result is more comprehensive and reasonable, and the hydroelectric development potential of an area can be reflected more truly.

Description

technical field [0001] The invention relates to an ecological suitability evaluation method, and in particular provides an evaluation method suitable for hydropower development projects considering water footprints. technical background [0002] Ecological suitability evaluation is a method to evaluate the suitability of land for a specific use by combining various factors such as geography, geology, hydrology, ecology, and meteorology. Traditional evaluation methods select impact factors from the three subsystems of environment, ecology, and social economy, and use fuzzy or hierarchical analysis methods to evaluate, and use GIS and other auxiliary means to show different suitability levels to provide technical and decision-making support for planning. However, the traditional evaluation method ignores the utilization and potential of water resources that should be paid special attention to in hydropower development projects, and does not fully consider the relationship betw...
