摘　　要：生态资产就是生态系统服务价值,通过生态系统的结构、过程和功能,直接或间接为人类提供产品和服务。对生态资产价值,以及与绿色发展之间的关系进行研究,具有重要的现实意义。利用神农架林区2009—2018年的土地利用数据,并结合陆地生态系统单位面积生态服务价值当量表,对2009—2018年神农架林区的生态资产价值总量进行分析研究。研究结果表明:(1)2009—2018年,神农架林区的生态资产价值呈下降趋势,生态资产价值从2009年的3480987.96万元下降到2018年的3465079.69万元,十年的时间神农架生态资产价值降低了15908.27万元,变化率为-0.46%。其中,林地的生态资产价值占比最大,贡献了97.66%的价值。(2)2009—2018年,神农架单项生态资产价值量均有所下降,其中,水文调节服务价值减少量最大,减少了21.61%;食物生产服务价值减少量最小,为1.69%。生态资产的非使用价值是使用价值的2.7倍,占比为73.10%。(3)运用BP神经网络模型,预测出2023年神农架林区的绿色经济将占比达到75.17%,生态资产价值与绿色发展显著相关,相关系数为0.9287(P<0.05),表明生态资产是绿色发展的根本和基础。保护神农架的生态资产,从而实现生态资产的增值。Ecological assets are the value of ecosystem services,which directly or indirectly provide products and services to human beings through the structure,process and function of the ecosystem.It is of great practical significance to study the service value of ecological assets and its relationship with green development.Based on the land use data of Shennongjia forest region from 2009 to 2018,combined with the ecological service value equivalent table per unit area of terrestrial ecosystem,it analyzed the total ecological asset value of Shennongjia forest region from 2009 to 2018.The results are as follows.(1)From 2009 to 2018,the service value of ecological assets in Shennongjia forest region showed a downward trend,and the service value of ecological assets decreased from 34809.87 million yuan in 2009 to 34650.79 million yuan in 2018.In ten years,the ecological asset service value of Shennongjia forest region decreased by 159.08 million yuan,with the change rate of-0.46%.Among them,the service value of ecological assets of forest land accounted for the largest proportion,accounting for 97.66%of the value.(2)From 2009 to 2018,the service value of single ecological asset in Shennongjia declined,among which the decrease of hydrological regulation service value was the largest,with a decrease of 21.61%;and the decrease of food production service value was the smallest,which was 1.69%.The non-use value of ecological assets was 2.7 times of the use value,accounting for 73.10%.(3)By using BP neural network model,it is predicted that the proportion of green economy in Shennongjia forest region will reach 75.17%in 2023,and the service value of ecological assets is significantly correlated with green development,and the correlation coefficient is 0.9287(P<0.05),indicating that green ecological assets are the foundation and foundation of green development.The protection of ecological assets in Shennongjia is conducive to the sustainable development of the region.
