多层次防护林体系生态服务价值评价方法

利用对和田地区多层次防护林区的调查研究,进行了林区生态服务功能价值的估算。评估结果表明,在和田玉北的多层次防护林体系中,生态服务价值居第一位的是生物多样性保护,总价值为2.12×106元,占总比例的43.09%;位居第二位的是净化大气环境,价值1.08×106元,占总比例的21.95%;调节大气组分价值排在第三位,为19.35%;涵养水源价值占总比例的11.85%,固土保肥价值量最小,仅占3.76%;在不同的治沙工程措施中,与天然稀疏植被封育区、草方格固沙-人工林区和人工林区相比,多种植物配置区土壤肥力较高,单位面积的价值最高,达到了266.67元/hm2。

Estimation of the ecosystem service value of the multi level shelter forest

Ecosystem service has become a focus in the field of ecology and ecological economics.In this paper,we used the research we did in Hotan to estimate the ecosystem service value of the Multi level shelter forest.From the results,we know that the first place of the ecosystem service value is the the preotection of the biodiversity,with the total value of 2.12×106 yuan.It’s occupancy is 43.09%.The purification of air environment take the second place,1.08×106 yuan with the percentage of 21.95%.The value of the components of the air conditioning take the third place,It’s occupancy is 19.35%.The value of conserving water take percentage of 11.85%.Tonservation of soil had a very small proportion,only take percentage of 3.76%.Variety of plants configurations has the most soil fertility among the different measures in the sand control project.It has reached 266.67 yuan/hm2.
