文中以分布于塔里木盆地的天然胡杨林为研究对象,使用影子工程法、机会成本法、水量平衡法、市场价值法等方法,对保护区内胡杨林的有机质生产、气候调节、土壤的形成与保护、水分调节(涵养水源)、对环境污染的净化、生物多样性的维持、以及娱乐文化价值7大类间接生态服务价值和木材产品、工业原料等两类直接生态服务价值进行了评估,并分析了结果,以其为减缓自然灾害、维护生态安全提供理论依据。结果表明:1)在塔里木盆地内,面积为39.54×104hm2的天然胡杨林保护区的生态系统服务价值平均为56.07×108元/年;2)研究区内胡杨林的间接服务价值为46.63×108元/年,直接服务价值为9.44×108元/年,直接服务价值约为间接服务价值的1/5;3)各项生态服务价值的大小顺序为:生产有机质>木材价值>净化环境>生物多样性维持>调节气候>土壤形成与保护>娱乐文化价值>水分调节>工业原料价值。塔里木盆地的胡杨林生态服务价值巨大,对社会经济的发展起着积极的促进作用,对塔里木河流域乃至整个盆地的综合治理极为重要。
In this paper, the natural Populus euphratica forest distributed in the Tarim Basin as the research object, using shadow engineering method, opportunity cost method, water balance method, market value method and other methods, the organic matter production, climate regulation, soil formation and protection, Water conservation (conservation of water sources), assessment of the value of indirect eco-service value of seven categories of recreational and cultural values and the value of direct ecological services such as timber products and industrial raw materials for the purification of environmental pollution and the maintenance of biodiversity, and analyzed As a result, it provides a theoretical basis for mitigating natural disasters and safeguarding ecological security. The results showed as follows: 1) In the Tarim Basin, the average ecosystem service value of natural Populus euphratica forest area with an area of 39.54 × 104hm2 was 56.07 × 108 yuan / year; 2) Indirect service value of Populus euphratica forest in the study area was 46.63 × 108 yuan / Year, the direct service value is 9.44 × 108 Yuan / year, and the direct service value is about 1/5 of the indirect service value. 3) The order of value of each ecosystem service is organic matter production> timber value> clean environment> biodiversity Maintain> Regulate climate> Soil formation and conservation> Recreational culture values> Moisture regulation> Value of industrial raw materials. The Hu Yanglin ecological service in the Tarim Basin is of great value and plays a positive role in promoting social and economic development. It is extremely important for the comprehensive management of the Tarim River Basin and the entire basin.
