摘 要:基于5期土地利用数据,探讨1980—2020年黄河流域河南段湿地景观格局的时空演变特征,运用CA-Markov模型预测2060年湿地格局,并利用效益转移法评估湿地生态系统服务价值(ESV)。结果表明:(1)黄河流域河南段湿地主要分布在黄河干流及支流两岸,其余区域湿地呈零星分布特征。(2)湿地面积以2000年为界呈先减后增的变化趋势,但总体仍减少13.18%,主要转化为耕地。预计2060年湿地面积将比2020年增加5.90%。湿地景观结构以2000年为界由趋于分散变为趋于聚合,2020—2060年将略趋于破碎。(3)湿地是研究区生态系统服务价值最高的地类。湿地总ESV变化趋势与其面积一致,总体减少129.26亿元。预计2060年湿地总ESV将比2020年提高50.24亿元。水文调节是湿地价值最高的生态系统服务功能。Based on five periods of land use data,this paper discusses the spatio-temporal evolution characteristics of wetland landscape patterns in the Henan section of the Yellow River Basin from 1980 to 2020,uses the CA-Markov model to predict the wetland pattern in 2060,and finally uses the benefit transfer method to assess wetland ecosystem service value(ESV).The results show that:(1)Wetlands in the Henan section of the Yellow River basin are mainly distributed on both banks of the main stream and tributaries of the Yellow River,while wetlands in other regions exhibit sporadic distribution characteristics.(2)The wetland area showed a trend of decreasing first and then increasing,but still decreased by 13.18%overall,mainly converted into cultivated land.It is expected that the wetland area in 2060 will increase 5.90%compared to 2020.The wetland landscape structure change was from being dispersed to being aggregated,and will tend to be slightly fragmented from 2020 to 2060.(3)Wetland is the land category with the highest ecological service value in the study area.The total ESV change trend of the wetland is consistent with its area,with an overall decrease of 12.926 billion yuan.It is estimated that the total ESV of wetlands in 2060 will increase 5.024 billion yuan compared to 2020.Hydrological regulation is the most valuable ecological service function of wetlands.
