基于生态系统服务价值评价的四川南河国家湿地公园优化策略研究

Researches on Optimization Plan of Sichuan Nanhe National Wetland Park Based on Evaluation of Ecosystem Service Value

为科学评价四川南河国家湿地公园建设成效,并进一步提出国家湿地公园优化策略,本文利用单位面积生态系统服务价值当量表,计算了四川南河国家湿地公园2005年至2018年生态系统服务价值变化。结果表明:四川南河国家湿地公园生态系统服务价值逐年增加,增长率达到40.4%,其中气候调节、生物多样性、美学景观和土壤保持方面价值增长率分别是330.7%、267.0%、201.1%和193.9%,气体调节、原料生产、维持养分循环、净化环境、水资源供给、水文调节增长率分别是176.9%、120.2%、94.2%、71.4%、31.7%、18.5%。基于以上研究,本文提出结合功能区划,逐步增加湿地面积,完善生态结构的优化策略。

In order to scientifically evaluate the effectiveness of Sichuan Nanhe National Wetland Park establishment, and to further propose an National Wetland Park superior strategy, the unit area ecosystem service value equivalent table was used to calculate the changes of ecosystem service value in Sichuan Nanhe National Wetland Park from 2005 to 2018. The results showed that the value of ecosystem services increased year by year in Nanhe National Wetland Park, with a growth rate of 40.4%. The growth rates of climate regulation, biodiversity, aesthetic landscape and soil conservation were 330.7%, 267.0%, 201.1% and 193.9%, respectively. Gas regulation, raw material production, maintenance of nutrient recycling, purification environment, water supply, and hydrological regulation growth rates were 176.9%, 120.2%, 94.2%, 71.4%, 31.7%, and 18.5%.Based on the above research, an optimization strategy was proposed in combining functional zoning, gradually increasing the wetland area, and improving the ecological structure.
