不同农林景观配置模式小流域生态服务功能价值评估
An Ecosystem Service Assessment on Watersheds of Different Agroforest Landscape Configuration Schemes
摘要
Abstract
Taking the watersheds of Jinfoping,Wuliwan,Miaozuigou,and Gaoxigou as research objects,which represented four different agroforest landscape configuration schemes in loess hilly regions,followed the standards of the "Specifications for Assessment of Forest Ecosystem Services in China",the service values of the eocological system were assessed from the aspects of water and soil conservation,carbon fixation,oxygen release,nutrient accumulation,air quality purification,and biodiversity conservation.The results showed that the total values and the values per unit areas of four watersheds were 2 477.5 × 104 yuan · a-1 and 71 102.9 yuan· hm-2 · a-1 for Jinfoping,3 851.7× 104 yuan· a-1 and 654 766.6 yuan· hm-2 ·a-1 for Wuliwan,4 919.6X104 yuan · a-1 and 67 612.1 yuan · hm 2 · a-1 for Miaozuigou,and 2 652.7×104 yuan · a-1 and 56 570.0 yuan · hm 2 · a-1 for Gaoxigou,respectively.The values of ecosystem service functions were mainly manifested by soil conservation,carbon fixation,and O2 release,and water conservation.For different agroforest landscape configuration schemes,the values were in the order of comprehensive ecological governance mode>ecological governance and economic orchard mode>ecological governance and crop grow mode>ecological governance and orchard with crop cultivation mode.关键词
