Abstract
林盘是成都平原特有的农村聚落单元,也是地域性的景观、生态和文化资源,其生态系统服务对于农户生产生活以及区域生态安全十分重要.本研究通过实地调查和农户问卷,估算林盘潜在和实际的生态系统供给服务价值,结果表明:(1)林盘内维管束植物种类106科254属310种,脊柱动物种类22目48科148种;(2)林盘的供给服务划分为20类,药用产品(145种)、园林产品(107种)、食用产品(53种)和木材产品(44种)种类较多,其他产品种类少,利用效率较低;(3)小、中、大型林盘实际供给服务价值量平均值约为2 867元/年·个、6 195元/年·个和9 842元/年·个;(4)郫县林盘实际供给服务价值量约为2 525.82万元/年,食用产品、园林产品和木材产品占比51.87％、22.64％和10.35％.
Linpan is the traditional rural settlements in Chengdu Plain,as unique landscape-ecological-cultural resources,its ecosystem services are very important for farmer's production and life,and also the protection of regional ecological security.The field survey and questionnaire survey data were used to calculate the potential and practical ecosystem provisioning services,and the results showed that:(1) There were 310 plants species belonging to 254 genera and 106 families in the survey area,in addition,also 148 animal species belonging to 48 families and 22 orders.(2) The ecosystem provisioning services of Linpan were divided into 20 types.According to the number of species for each type,145 species were medicinal plants,107 species were garden plants,53 species were food plants,44 species were wood products,and the number of species of other types was small with low practical use efficiency.(3) The average value of practical provisioning service provided by small Linpan was 2 867 yuan per year,among medium and large Linpan was 6 195 yuan per year and 9 842 yuan per year.(4) According to the valuation result,simultaneously,the economic values of practical ecosystem provisioning services were 2 525.82× 104 yuan per year,among which the value of service provided by food,garden plants and wood products were higher than others,accounting for 51.87％、22.64％ and 10.35％.
