| 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. |
