The Research On Natural Reserve Landscape Services And Values Assessments

Man-land relationship is the core issue of geography, economics and landscape ecology, also is the important content of environment management. which is specially expressed landscape pattern and ecological assessment study in landscape ecology. Although researchers launched a large number of studies about the landscape pattern spatial characteristics, the assessment system and methods of ecosystem services, but the problem about the processes acting on the landscape system service functions and the internal mechanism of the ecosystem construction-value-service contact. This paper introduces the concept of landscape services, and proposes the research system of landscape construction-service-value. Meanwhile, this paper will take Jiuzhaigou Nature Reserve as the research object, and take the theory of landscape ecology as a basis. By expanding landscape pattern and its dynamic change research, building the landscape services index system of Jiuzhaigou Nature Reserve, analyzing s the spatial characteristics of landscape service, estimating recreation services for the object value in order to achieve expression of spatial correlation construction, which will be the new methods and ideas for landscape construction and function.This paper analyzed the Jiuzhaigou Nature Reserve landscape pattern, using three remote sensing image which are made in different years—1997,2004,2012. The conclusions are following:Ⅰ Jiuzhaigou Nature Reserve landscape pattern is more stable and more balanced construction of different regions of the construction. Woodland landscape is the most important type of landscape,whose LPI index is very obvious. The construction land is the smallest footprint whose LPI is the lowest. Ⅱ The Landscape stability in Zharu valley and Pujilongli valley is the highest, while the Landscape stability in Zhawa valley and Danzu valley is the lowest.Through building the Jiuzhaigou Nature Reserve, landscape services index system and evaluation criteria, assessing the system technology landscape in use of participatory geographic information, the conclusions are following:Ⅰ There is a certain space and has a strong agglomeration in Different landscape services. Views of residents perceived mainly from the vicinity of the settlements, landscape service point density decreased with the increased and settlements distance. Ⅱ Landscape Services category unevenly distributed in different regions. The different layer distribution in the core area of the landscape services the lowest density.Ⅲ The density distribution and dispersion of the landscape indicators was a significant positive correlation. Other rare animals density and LSI in the region are the largest, and the space distribution of the highest dispersion, followed by forest recreation and ornamental water body; spiritual beliefs, sewage treatment, folk festivals and camping in the lowest density and spatial cohesion, more even distribution of agglomeration.This paper take recreation services as example, using CVM, and estimates the recreational value of the Jiuzhaigou Nature Reserve. In614valid questionnaires, the willingness to pay is73%and the recreational value of Jiuzhaigou Nature Reserve in2011is732million. The recreational value of mountain lakes, waterfalls, beaches flow, rare animals, forest recreation, geology beauty, Tibetan villages and ornamental plants is226million,166million,111million,115million,77million and37million.Finally, this paper, by analyzing the amusement value, calculate the value of units of different recreation services. The Tibetan villages get the highest unit value, followed by geological beauty. The high unit value of recreation service points mainly concentrated in the valley areas of Shuzheng valley, Rize valley, Zechawa valley and Zharu valley. The distribution of the recreational value of the geographical unit also is the value of the distribution of the different land use types, then achieve the landscape value in the expression of the spatial construction.The core zone, buffer zone and experimental zone has been the main basis of the partition management for nature reserves in China. The results of landscape structure, landscape services and value (recreation) spatial analysis can be seen that the services and values are not entirely from the experimental zone center to spread around. Landscape services and values distribute a new perspective to the protection and management of environmental management in the nature reserves, to promote nature reserve for environmental protection and sustainable development.
