Study On The Comprehensive Evaluations Of Landscape Resources In Gansu Liancheng National Nature Reserve

Starting with the defination , the classification and the evaluation goal of the landscape resoures, the thesis summarized the predecessor's research work, which included the angle, method, content and model of the landscape resource evaluation. On the basis mentioned above, according to the information collected and the relevant data investigated pratically, applying the principal theories of forest tourism resource, tourism psychology,forest ecology, landscape aesthetics and the methods of analytical hierarchy process(AHP) and polynomial regression model,an evaluation system with twenty-two indexes and other evaluation system with seven indexes selected from quality of landscape resources,the conditions of environment,the conditions for resources development and construction, were established to evaluate quality of landscape resources in the Liancheng National Nature Reserve of Gansu Province,China from two different layers: the whole Nature Reserve, the nature valleyes. The main results and conclusion were summarized as follows:(1)On the comprehensive evaluation layer, according to the result of ordination of comprehensive evaluation system of landscape resources by means of AHP, the weight value of quality of landscape resources was the highest in sub-goal layer of comprehensive evaluation of landscape resources;the environmental condition was less important;The last was the conditions for resources development and construction;according to the result of general ordination of comprehensive evaluation system of landscape resources by means of AHP, the weight value of forest vegetation was the highest among 22 grass-roots indexes,which was the essential of Nature Reserve;mountain topography was less important,which constituted the basic framework of landscape resources with forest vegetation;the weight value of water landscape was the third;the telecommunication,water supply, electric power and local products had slight influence on the comprehensive evaluation of landscape resources。(2)the comprehensive evaluation of landscape resources in the Liancheng National Nature Reserve was second grade,this indicated that the landscape resources in this reserve was abundance and had great development potential. The favorable conditions for landscape resources in Liancheng National Nature Reserve of Gansu Province were forest vegetation , mountain topography, water landscape and the beautiful natural environment.The disadvantages of landscape resources in Liancheng National Nature Reserve of Gansu Province were insufficient infrastructure and tourism services, low popularity, less Human landscape.(3)On the nature valleyes layer, according to the evaluation result of the nature valleys, it shows that the integrated score of the Tulu valleye (7.5197) is the highest, among the 15 valleyes in the Liancheng National Nature Reserve of Gansu Province, then the orders were as follows: the second is Gangzi valleye (6.7789), Shuimo valleye (5.9940), Zhulin valleye (5.8534),Shangxi valleye (5.7492), Xiaogangzi valleye (5.7450),Tiecheng valleye (5.0565), Zhinanbei valleye (4.9929), Ga dasi valleye (4.5474, Xiaoxinger valleye (4.5554),Jingzhi valleye (3.9719),Xiaxi valleye (3.8917),Pengzi valleye (3.6570),Quhongtu valleye (3.6486),SuDu valleye (3.2128).(4)Tulu valleye,Gangzi valleye,Xiaogangzi valleye,Zhinanbei valleye and Gadasi valleye were appropriate to carry out eco-tourism,but other valleys in the core area or the buffer zone should not be carried out.
