An Study On Forest Landscape Pattern Of Pang Quangou Nature Reserve In Shanxi Province

With 2004 SPOT5, 1999 Landsat7ETM+, 1990the Landsat5TM satellites images data, based on the geographic information system (GIS) and the remote sensing (RS), we analyzed the current situation and dynamic of forest landscape carries on the analysis using the landscape pattern index to Pang Quangou. Then its results will put forward proposal to forest landscape plan, for improving the landscape quality and the management level.With the data of three courses of RS, the paper conducted analysis to the forest landscape distribution and the dynamic process of the Pangquangou area, which concluded that the forested land as matrix of the Pangquangou area plays the dominant role in controlling the landscape general structure, functions and the dynamic processes. The results of the dynamic analysis indicate that with the expansion of the average scale of the forested land patch, the form of the patch turns to be more complicated, the landscape diversity declined, and the eveness index tended to be at the low level,explaining that the dominant types of the landscape (Larix principis-rupprechtii forest and the spruce forest) gradually strengthened its dominant positions to make the general landscape variation level lower.The Reserve has divided three function areas, namely core, buffer and experimental area. Core area has largest average scale, least landscape types; experimental area has all types in reserve, and its area biggest, the patch number is largest. The patch shape of core area is most complex, experimental area is more regular. The patch density of core area is smallest, next is the experimental area. The patch density of buffer area is biggest, the number of landscape types have main influence on the of function area. core area has least landscape types, and has smallest diversity index; experimental area has most landscape types and smallest diversity index. The buffer area has the highest dominant index and the lowest eveness index. The landscape pattern dynamic analysis of fuction areas indicated that: the number of landscape types in 2004 core area is less then in 1990 and 1999. As a whole, the change of core area average scale is firstly increase and then reduce,while the experimental area continuously reduces. Regardless of core area or experimental area, patch density and edge density are increasing in all year by year, but experimental change is more. The diversity of experimental area is higher than core area, The diversity of core area and experimental area in 2004 are lower than other years. From the eveness index, core area in 2004 is highest, experimental area is highest in 1999 and lowest in 2004, which show the heterogeneity of core area is lowest, the experimental area is highest.It is clear about the protection principle and the goal on the overall plan in 2000 of Pangquangou nature reserve. The overall plan in 2000 made an adjust on fuction area distribution, which are core area, buffer area and experimental area. The change is reasonable, the science. Moreover, based on 2000 overall plan's shortcoming, this article put forward the proposal from the forest road landscape and the eco-tourism developed.
