The Construction Of Forest Recreational Band And Typical Forest Landscape Resources Evaluation In Beijing

This thesis taking silviculture, landscape ecology, forest aesthetics, forest recreation as the theoretical basis, based on the Beijing area of forest landscape, according to the 2007 Beijing 1:100 000 SPOT 5 satellite remote sensing image,2004 regional forest resource gradeâ…¡survey data, combined with field surveys, surveyed and analysised the forest landscape resources situation in Beijing. The main contribution of the thesis is summarized as follows:(1)According to a lot of literature and field survey results, considering the distribution of forests in Beijing area, road conditions, tourist preferences and other factors, combined with 3S technology, the construction of forest recreational band was presented,which was seted forest as the background. Four belts were planned and each of them has individual advantages and characteristics. They were Yanqing-Changping forest recreation band with a core of Songshan nature reserve, Miyun-Huairou forest recreation band with a core of Yunmengshan forest park, Fangshan-Mentougou forest recreation band with a core of Donglinshan, and Miaofengshan forest recreation band with a core of Miaofengshan scenic spot. The planning principles, guiding principles and specific content were proposed. Combined with the planting of some theories and methods of cultivating, forest landscape resources in Beijing were put forward the reform measures.(2)This paper analyzed the way to adjust the layout of forest recreation band, it also analysed the category of forests distribution informations. Base on it, this paper pointed out that the shelter forest should play its role in forest multifunctional benefit. The main function of shelter forest should change from the environment ecological function to livability leisure and recreational function. The proportion of scenic and recreational forest should be adjust in the area of forest recreation band. After adjustment, the area of the scenic and recreational forest will increase from52253.6 hm2 to 147037.08 hm2, and the proportion will rise from 8.44% to 23.74%.(3)Combining with AHP and fuzzy comprehensive evaluation method, the forest landscape resources, which were in the region of the forest recreation band, have been analysed and evaluated. This paper selected forest composition, visual landscape effects conditions, recreational development conditions and other factor as evaluation index factors, structured matrix to obtain the indicator system various targets weight, and thus establish the forest landscape resources evaluation index system and fuzzy evaluation model. The typical forest landscape resources which were in the key region of forest recreation band, were quantitatively analyzed and estimated.The research provided much reference value for developing, utilizing and managing forest landscape resources and it had practical significance to forest recreation development and ecological environment protection in Beijing area.
