Abstract [目的]以元谋县为研究区,基于生态学、RS和GIS理论和方法,研究干热河谷林地利用及生态系统服务价值的变化特征,以期丰富干热河谷林地生态研究,为区域生态环境调控提供理论依据。[方法]以2008年Landsat7ETM及2016年Landsat8OLI2期遥感影像、国家基础地理信息系统及ASTERGDEM数字高程模型为数据源,利用ENVI和ArcGIS软件对2期遥感影像进行解译,获取林地土地利用数据,分析林地的时空特征;调整林地生态系统服务当量因子系数,计算单位面积农田食物生产功能价值及单位面积林地生态系统服务价值系数,分析林地生态系统静态价值特征及其变化;以支付能力指数、支付意愿指数和环境能力指数为参数构建林地生态系统服务动态价值调整系数,分析林地生态系统服务动态价值特征及其变化。[结果]林地主要分布在研究区南部和东部的中高山,在西部、西南部和北部及东部边缘的中高山有少许分布,在河谷坝区有零星分布;2008--2016年林地面积增长了64.24hm2,变化幅度达到11.42%;有90.53km2的林地转为非林地,有154.77km2非林地转为林地。林地向草地转移了73.61km2,草地向林地转移123.11km2;2016年研究区林地生态系统服务静态价值为14.97亿元,较2008年的13.44亿元提高了1.53亿元。2016年林地在研究区生态系统总静态价值的比例为56.41%,较2008年的51.73%提高了4.68%;2008年和2016年林地生态系统服务动态价值分别为4.758亿元和9.027亿元,仅为同期林地生态系统服务静态价值的35.40%和60.30%。[结论]研究区林地面积迅速增长,林地与非林地相互转换频繁,林地净增长明显;林地面积的增长提升了生态系统服务的静态价值。林地的单项生态系统服务价值中,土壤形成与保护、气体调节和生物多样性保护的价值最大,食物生产的价值最小;林地生态系统服务动态价值虽然远低于静态价值,但其变化幅度明显高于静态价值。高生态系统服务价值的林地对社会和环境调节能力的增长更为敏感。

Abstract_FL [Objective] Yuanmou county was selected to studied the change of forest land utilization and forest ecosystem service value in the dry-hot valley so as to enrich forest ecology research and provide theoretical basis for regional ecological environment regulation.[Method] Taking remote images of Landsat 7 ETM in 2008 and Landsat 8 OLI in 2016,national basic geographic information system and ASTER GDEM digital elevation model as data sources,the ENVI and ArcGIS software was used to interpret the remote sensing images,obtain the forest land-use data,and to analyze the temporal and spatial characteristics of forest land,and calculate the function value of farmland food production per unit area and coefficients per unit area of forest ecosystem service value.Then,the forest ecosystem service value and its changing characteristics were analyzed.The adjustment of coefficient of dynamic value of forest ecosystem service was constructed on the basis of payment ability,willingness to pay and land by using ENVI and ArcGIS software.Forest ecosystem equivalent coefficients were adjusted,as well as environmental capacity as main parameters in order to analyze the dynamic value characteristic and its change of forest ecosystem service.[Result] Forest land is mainly distributed in southern and eastern parts of the middle-high mountains in the study area.A small amount of forest scatters in western,southwest,north and eastern foothills of the middle-high mountains.Few parts are sporadic in the valley dam area.Forest area increased by 64.24 hm2,and variation range reached 11.42% from 2008 to 2016.The area of forest land converted into non-forestland reached 90.53 km2,while the forest area converted from other land-use types was 154.77 km2.There waere 73.61 km2 of forest land converting to grassland and 123.11 km2 converted from grassland.In 2016,the static value of forest ecosystem service in the study area was (¥) 1.497 billion,an increase of (¥) 153 million over (¥) 1.344 billion in 2008.In 2016,the proportion of forest land in the total static value of regional ecosystem service in the study area was 56.41%,which increased by 4.68% compared with 51.73% in 2008.The dynamic value of forest ecosystem service in 2008 and 2016 were respectively (¥) 475.8 million and (¥) 902.7 million,which only accounted for 35.40% and 60.30% of static value of forest ecosystem service in the same period.[Conclusion] The forest land area increased rapidly,the forest land and non-forest land converted to each other frequently,leading to an obvious net increase of forest area.The area increase of forest land resulted in static value growth of forest ecosystem service.Among individual value of forest ecosystem service,soil formation and protection,gas regulation and biodiversity conservation scored the high-est,while the food production had the lowest score.Although the dynamic value of forest ecosystem service is far less than the static value,the range of dynamic value change is obviously higher than that of static value.The forest land with high ecosystem service value is more sensitive to the growth of social and environmental regulation.
