中文摘要：

运用LNOPT平台和GIS软件对5种生态系统服务功能进行优化分析,构建研究区的生态景观优化模型。运用生态系统服务价值当量因子方法对怀来县土地利用总体规划前、土地利用总体规划后和土地利用景观优化后的生态系统服务价值进行计算和分析。结果表明,怀来县现状生态系统服务价值总量9.533 3×108元,经土地利用总体规划之后,生态系统服务价值总量9.438 3×108元,减少了1.00%。对怀来县的土地利用景观生态优化后,生态系统服务价值总量9.928 3×108元,增加4.14%。进行土地利用总体规划后,土地各单项生态系统服务价值除了食物生产功能增加外,其他均有所减少。经景观优化后,各单项生态系统服务价值量都有所增加。研究区的景观生态优化模型能取得一定的生态效应,可作为下一轮土地利用总体规划和地区发展的参考。

英文摘要：

The LNOPT platform and GIS software were used to analyze five ecological functions and build the ecological landscape optimization model in the study area. The equivalent factor method of value of ecosystem services was used to calculate and analyze the value of ecosystem services before the overall plan for land-use,land-use planning and after land-use.The results showed that, the total value of ecosystem service was 9.533 3×108yuan in Huailai. After land-use planning, the total value of ecosystem services became 9.438 3×108yuan, a decreasing of 1.00%. After optimizing land use landscape ecology, the total value of ecosystem services was 9.928 2×108yuan, increasing 4.14%. After the land use planning,the individual service values of land all had been reduced except the food production. After optimization of the landscape, the individual values of ecosystem service all had been increased. Landscape ecological optimization model of the study area could achieve certain ecological effects. It could be used as a reference for the next round of land use planning and regional development.
