Forest Ecosystem Service Value And Dynamic Evaluation Research Of The Coastal Economic Development Zone

Coastal economic development zones play an important role of " engine " in the national economic development.It has an important role in promoting the economic development of Fujian of the west side of the Straits Economic Zone.So it has a very important practical significance to clioose Zhangzhou Gu Lei Harbor Economic Development Zone as the research object.Based on taking Gu Lei port economic development zone in Zhangzhou in2011the second class survey data of forest resources, as well as the local hydrological soil collected by the related data, using GIS technology and method, the direct market method and so on, taking gu lei port economic development zone in2011estimated forest ecosystem serviee function value; And quoting system dynamics to construct benefit model of forest ecosystem service function, through the model prediction in2011-2020development zone forest ecological benefit, for the local ecological serice function value dynamic monitoring provides the basic data, in order to better safeguard forest ecological and economic development, to realize the people to harmony, the sustainable development of environment. Specific as follows:(1) In the second class on the basis of the survey data of forest resources, through analyzing the characteristics of the local, to forest ecosystem service function indexes and reasonable use of the method and the data of forest ecosystem service function value to provide the quantitative calculation of science.(2) According to the LY/T1721-2008specifications for assessment of forest ecosystem services, the system elaborated forest ecosystem service function assessment index system, assessment method and application of formula.(3) Analyzes the evaluation of forest ecosystem service function value needed to use the method and index system, combining with the characteristics of regional forest. the forest zone of the quantitative assessment of ecosystem service function value, the result shows that the study area total forest ecosystem service value is3.93×108yuan/a, the water conservation value0.20×108yuan/a,, accounting for5%of the total value; Solid earth protecting fertilizer value of0.72×108yuan/a, accounted for26%of the total value; Forest biodiversity value of0.0517×108yuan/a, accounting for more than1%; Fixing carbon and releasing oxygen value of0.3521×108yuan/a, accounting for9%; Purify environment value is2.30×108yuan/a, accounting for59%of the total value. Take gu lei port economic development zone of forest ecosystem service value is the size of the order:purify environment soil> solid and fertility value>fixing carbon and releasing oxygen value of water conservation value of biodiversity value.(4) Through the system dynamics simulation model, predict take Gu Lei port economic development zone forest various forest service function change trend. Development zone of the forest all the four of the five service function benefits have shown the tendency of increase. Coniferous forest, forest, economic forest benefit all show similar change trend, just because of all the four forest age structure have differences, all the four forest.
