摘要
【目的】对大兴安岭南麓山区退耕还林工程进行生态系统服务功能评估和空间格局研究,并分析其影响因素,为大兴安岭南麓山区退耕还林工程结果的巩固及可持续发展提供科学依据。【方法】以截至2017年底大兴安岭南麓山区退耕还林工程资源数据集和退耕还林工程生态连清数据集为基础,依据《森林生态系统服务功能评估规范》(LY/T1721—2008)和《退耕还林工程生态效益监测与评估规范》(LY/T 2573—2016),采用分布式测算方法进行生态系统服务功能量化评估,在此基础上,结合大兴安岭南麓山区地形、多年平均降水和气温数据进行影响因素分析。【结果】大兴安岭南麓山区退耕还林工程生态效益价值为134.47亿元·a^-1,其中涵养水源、净化大气环境、固碳释氧和森林防护功能排在前列;空间分布格局整体趋势为由西向东逐渐递减,区内3个省份以内蒙古各项功能最佳;大兴安岭南麓山区退耕还林工程主要生态系统服务功能均与3个环境因子成显著相关关系。【结论】大兴安岭南麓山区退耕还林工程各项生态系统服务功能发挥了明显的生态效益,为区域生态安全和可持续发展提供了保障;大兴安岭南麓山区退耕还林工程生态系统服务功能空间格局,不仅受退耕还林工程资源面积影响,同时还受到地形、降水和气温的影响,其中,多数功能生态效益的发挥主要受到地形条件的制约。
【Objective】To study the spatial pattern of ecosystem service function of Grain for Green Projectin the southern piedmont region of Daxing’an Mountains.It provides a scientific basis for the consolidation and sustainable development of the results of the project.【Method】Based on the resource data of GTGP in the southern piedmont region of Daxing’an Mountains by the end of 2017,according to the Specifications for assessment of forest ecosystem services in China(LY/T1721-2008)and Ecological Standard Monitoring and Evaluation of Grain for Green Project(LY/T 2573-2016),the ecosystem services function was quantitatively assessed by distributed calculation method.On this basis,combined with the topography of the southern piedmont region of Daxing’an Mountains,multi-year average precipitation and temperature data to analyze the influencing factors.【Result】Quantitative evaluation of service function shows that the ecological benefit value of the project is 13.447 billion yuan per year,among which water conservation,air purification,carbon sequestration oxygen release and Forest protection rank the top three.【Conclusion】The ecosystem service function of Grain for Green Projectin the southern piedmont region of Daxing’an Mountains has played an obvious ecological benefit,which provides guarantee for regional ecological security and sustainable development.The spatial pattern of ecosystem service function is not only affected by the area of the project resources,but also by the terrain,precipitation and temperature.Most of the functional ecological benefits are mainly restricted by the terrain conditions.
