摘要
以吉林扶余洪泛湿地省级自然保护区为研究区,研究保护区生态服务功能的时空变化,采用InVEST模型对该区域的水源涵养、水土保持、生境质量及固碳进行评价,以评价其2015-2020年生态服务功能的时空分析。结果表明:2015-2020年保护区总水源涵养量分别为7934351.06、8075961.75 m^(3),经两期数据比较得出,水源涵养有提高,变化率为1.78%,保护区湿地生态环境在水源涵养方面起到了巨大作用。2015-2020年保护区的总水土保持量分别为575289.07、4495027.15 m^(3)t/a,经两期结果比较得出,水土保持有明显下降,变化率为-13.95%,水土保持计算及其结果受降雨侵蚀力因子大小影响较大,导致一定程度上造成两期水土保持结果变化情况较大。2015-2020年保护区固态值分别为4373.19、4799.45 tC,变化率为9.75%,总固碳量呈现正向变化。2015-2020年保护区生境质量大部分表现良及优。保护吉林扶余洪泛湿地省级自然保护区的生态系统服务功能,无论在洪泛平原湿地和野生珍稀濒危鸟类(东方白鹳、丹顶鹤、大鸨)及其栖息地保护及生态质量,发挥着越来越重要的生态效益、社会效益和经济效益,为自然保护区的保护与利用提供参考。
Taking the provincial nature reserve of Jilin Fuyuhong Wetland as the research area,the spatial-temporal changes of ecological service functions of the protected area are studied.Water conservation,soil and water conservation,habitat quality and carbon sequestration in the region were evaluated using InVEST model to evaluate the temporal and spatial analysis of ecological service functions from 2015 to 2020.The results show that:from 2015 to 2020,the total water conservation volume of the protected area was 7934351.06 m^(3) and 8075961.75 m^(3).After comparison of the two phases of data,the water source conservation increased,and the change rate was 1.78%,which played a huge role.From 2015 to 2020,the total soil and water conservation in the protected area was 575289.07 m^(3) t/a and 4495027.15 m^(3) t/a.After two stages of results,the soil and water conservation decreased significantly.The change rate was-13.95%.The calculation of soil and water conservation and its results were greatly affected by the size of rainfall erosivity factor,which resulted in a large change of soil and water conservation results in the two periods to a certain extent.From 2015 to 2020,the solid state value of the protected area was 4373.19TC and 4799.45TC,respectively,with a change rate of 9.75%.From 2015 to 2020,most of the habitat quality of the protected area performed well and excellent.To protect the ecosystem service functions of Jilin Fuyuhong Wetland Provincial Nature Reserve,it plays an increasingly important ecological,social and economic benefits in flood plain wetlands and wild rare endangered birds(Oriental White Cycles,Danchong Cranes and Daji)and their habitat protection and ecological quality,which provides a reference for the protection and utilization of nature reserves.
