The ecosystems were classified into 13 types including valley rain forest, mountainous rain forest, tropical monsoon forest, mountainous coppice forest, mountainous ever green forest, tropical coniferous forest, shrubs, plantation, timber forest, windbreak forest, mangrove, savanna, and crop land, and then, the regulation services and their economic values of Hainan Island ecosystem were assessed and evaluated by terms of water-holding, soil-conservancy, nutrient cycle, C fixation, and windbreak function.
研究表明,2004年海南岛基于生态系统服务功能的绿色GDP为1042.80—1072.84亿元。其中传统GDP为769.36亿元、环境污染经济损失为10.54亿元、生态GDP为283.98—314.02亿元。经分析可知道:海南岛由于工业并不发达,其环境污染损失并不严重,只占传统GDP的1.4%;然而海南岛生态系统服务功能所提供的价值却是非常大,其中生态GDP是传统GDP的37%—41%。

Based on the concept and the theory of forest park and forest tourism, development advantages of Hanzhong forest park were identified as follows: i through the past several years'development, forest tourism products were getting so abundant gradually that a fundamental scale was formed, with three national forest parks as well as three province parks founded; ii the idea of"tourism stimulation"was determined as the development strategy in the province since forest tourism played an increasingly significant part in the development of Hanzhong economy and society; iii geo-topographically, forest park in Hanzhong not only possess similar precipitous view of Qinling, but also equally splendid scenery of Bashan; iv hydrologically, the landscape had a lasting appeal as that in south China to some extend; v the forest located in the best site of the same latitude; vi with the opening of Xihan expressway, access to Hanzhong was upgraded prominently, which made the park a garden of Xi'an and a resort for many citizens.

There are some questions such as forest fire model selection, forest fire model updating, verifying simulation accuracy and so on in traditional forest fire spreading system. Study purpose is to build an innovative forest fire spreading simulation system based on DDDAS in this paper. The system can increase precision of forest fire spreading simulation by model base, model selection, model updating and so on. It can provide a strategic decision for forest fire save and new technologies demonstration for other related field of research. The research encompasses several major topics:(1) This paper brings up the term of dynamic data driven forest fire spreading simulation system and supplies new research approach and thought for forest fire spreading simulation study. The system framework was brought.
