【摘要】 生态系统服务价值理论是目前生态学、地理学等环境科学研究的热点问题，将生态服务价值理论应用于深居内陆腹地，气候干旱的和田河流域，计算其天然森林生态系统的服务价值的评估，是本论文研究的中心，也是创新点所在。在大量阅读相关文献和实地收集资料的基础上，采用科学的方法和合理的指标，对和田河流域森林生态效益进行评估，较为细致得计算了森林生态系统7大类间接生态服务价值和5类直接服务价值。经过对和田河流域森林生态系统定量评价、分析、研究得出以下主要成果：（1） 和田河森林生态系统服务价值总值是2960.62-2963.19亿元/a。 研究区森林单位面积的服务价值比全国水平高。胡杨林、柽柳、胡杨疏林地，3种类型的森林生态系统，以柽柳灌木林的单位面积生态服务价值最高，其次是胡杨林。本文的研究结果表明：在干旱区，社会经济发展、资源的开发与利用，始终要以生态环境的保护为前提；以生态服务价值的计算结果为依据，向环境管理部门提出环境管理建议若干。更多还原

【Abstract】 The ecological service value theory is the researching focus of Ecology and Geography today. Using the ecological service value theory to evaluate the forest in Khotan drainage area is the center of my paper; in the meantime, it is also the creative point.After reading plenty of relative literatures and collecting lots of first-hand datum, adopting rational methods and indexes, worked out the evaluation of the forest in Khotan drainage basin, including eight indirect service value and five direct service value .After rational evaluating, the author put the main fruits as following:The total ecological service value of the forest ecological system in Khotan drainage basin is 296.062-296.319 billion Yuan annually.The ecological service value of the researched forest is higher . For these three forest ecological system—the natural Popuius euphratica forest, Tamatix spp forest, and the thin natural Popuius euphratica forest, the Tamatix spp forest possesses highest ecological service value.The results above proclaimed clearly: in the weak inland arid area, the protection of the environment is the very foundation of the development of society and resources exploitation and utility, and from this point, the author advanced some new suggestions of environment management.更多还原
