摘要：针对以盐渍化影响和风沙活动为特征的北方农牧交错带,研究其生态系统服务功能空间差异及其流变机制,有助于明确服务提供区(SPA)与服务受益区(SBA)之间的空间关系,制定跨区生态补偿方案。采用混合单粒子拉格朗日积分轨道(HYSPLIT)模型和源贡献潜势(PSCF)模型,模拟了大型盐碱沙尘源地(安固里淖干涸盐碱湖)防风固沙生态系统服务(SSS)对风蚀的影响,确定了在土地覆盖、人口和国内生产总值(GDP)方面的辐射效益,并以辐射效益结果为依据提出跨地区的横向生态补偿方案。结果表明:在2015年,安固里淖干涸盐碱湖生态系统SSS效益显著,固沙量达到367.93万t;研究区SSS传输路径向东部延伸,主要影响我国华北和东北地区,SBA土地面积为189.37万km^2,占全国总面积的19.66%,受益范围包括北京市等15个省(市、区),是研究区面积的41167倍;受益人口达5.27亿人,受益GDP总量为28.37万亿元;研究区生态系统提供的SSS使得SBA降尘量减少147.17万t,直接经济效益达44.26亿元;研究区投入生态建设的资金应由北京市等15个受益省(市)共同承担,黑龙江省和内蒙古自治区补偿金额最大,其次为河北省、吉林省和辽宁省等,浙江省需支付的生态补偿金额最少。本研究通过横向生态补偿促进生态建设,以减轻由土壤风蚀造成的损害,可为有关部门的政策决策者提供参考。
For the northern farming-pastoral zone characterized by salinization effects and wind and sand activities,studying the spatial differences in ecosystem service functions and their rheological mechanisms can help to clarify the spatial relationship between service provision area(SPA)and service benefit area(SBA)and cross-regional ecological compensation schemes.The hybrid single-particle Lagrangian integrated trajectory(HYSPLIT)model and the potential source contribution function model(PSCF)were used to simulate the impact of the sand-stabilization ecosystem service(SSS)of the large-scale saline-alkali sand source area(dry saline-alkali lake in Angulinao)ecosystem on wind erosion and SBA.The radiation benefits in terms of land cover,population and gross domestic product(GDP)were determined,and cross-regional horizontal ecological compensation schemes were proposed based on the results of the radiation benefits.The results showed that the SSS of ecosystem in the study area was significant,and the amount of sand fixation reached 3.6793 million tons;the transmission path of SSS extended to the east,mainly affecting North China and Northeast China.The land area of SBA was 1.8937 million km^2,accounting for 19.66%of the total area of China.The benefit scope included 15 provinces(cities and districts)such as Beijing,which was 41167 times of the research area itself;the beneficiary population reached 527 million people,and the total benefited GDP was 28.37 trillion yuan;the ecological restoration of saline-alkali land in the study area reduced the amount of dust in the beneficiary areas by 1471700 t,and the direct economic benefit reached 4.426 billion yuan.The ecological compensation fund was jointly undertaken by 15 beneficiary provinces(cities and districts).Heilongjiang Province and Inner Mongolia Autonomous Region had the largest compensation amounts.Followed by Hebei Province,Jilin Province,Liaoning Province and other provinces,Zhejiang Province had to pay the least amount of ecological compensation.Based on the theory of ecosystem service flow,the SSS provision-transmission-benefit mechanism was analyzed,the quantitative relationship between SPA and SBA was studied,and the actual beneficiaries and benefits were determined.Through the application in dry saline-alkali lake in Zhangbei County,Hebei Province,this work can provide policy makers with a reference to promote ecological construction through horizontal ecological compensation and reduce the damage caused by soil wind erosion.
