The results show that the cultivated land area in Wanzhou will slightly decreased while the construction land will slightly increased,forest land will increased dramatically,and it is difficult to improve the ecosystem service value by single increasing the wetland area.Grassland ecological restoration and increasing orchard area will improve the ecosystem service value by comprehensive treatment of geological hazards and soil loss.The ecosystem service theory value in Wanzhou is 11.89 billion yuan each year,the correction value is 10.64 billion yuan each year,and the present value is 9.65 billion yuan each year.This shows the ecological restoration has good economical efficiency.The optimization of land use structures based on ecosystem service value could satisfy the development of social economy with land demand,and realized the benefit of ecology and economy inphase,the study supported a new way to solve the key technical problem in land use programming in China.
计算结果表明:(1)规划期内万州区耕地面积略有减少,建设用地面积有所增加,林地面积有较大幅度增加,大规模增加湿地面积提高土地生态功能价值则难以实现;(2)地质灾害与水土流失综合治理、草地生态系统修复以及适当增加园地面积,能够提高万州区土地生态功能价值;(3)万州区土地生态经济理论价值为11888亿元/a,修正价值为10644亿元/a,均高于现状值9653亿元/a,土地生态修复与建设的生态经济效益可观;(4)基于生态系统服务价值的土地利用结构优化,能够满足社会经济发展对土地的需求并同步实现生态经济效益的最优,为解决土地利用规划中的关键技术问题提供新的方法。
