Abstract


Landscape Pattern Change Research is the core of landscape ecology, the study area can be accurately grasp a dynamic process of landscape resources for further development of landscape ecological planning and construction is of great significance. In this paper, Gushan Scenic Area as the research object, using the 2001 and 2007 two Gushan Scenic Area TM satellite images, the use of modern means of GIS technology in landscape ecology Software FRAGSTATS support, draw Gushan Scenic Area average patch area, mean patch shape index, patch density, fragmentation index, distribute and adjoining index, diversity index, dominance index and evenness index and other indicators of a variety of landscapes, and thus on Gushan Scenic Area landscape ecological classification, basic ecological characteristics description, landscape elements and characteristics of plaque dynamic change of landscape pattern and landscape changes occur further analyzes the reasons for the Gushan Scenic Area a better development of eco-tourism planning and landscape protection provides a scientific basis. The main results are as follows: 1, landscape ecological classification results showed that: Gushan Scenic Area in 12 categories landscape, scenic pine forest landscape area much larger than the other 11 kinds of landscape types, accounting for the proportion of total area of ??more than half of the entire Scenic Area landscape pattern of dominant position. Pine forest landscape, landscape conifer and broadleaf forest landscape is the area's largest three kinds of landscape types, three types of landscape scenic area of ??the total area of ??79.01%; smallest water landscape. Gushan Scenic Area entire forest area of ??4156.64 hm2, accounting for 83.61 percent scenic area, the entire area of ??vegetation coverage is high. 2, plaques characteristic landscape elements analysis results showed that: Gushan Scenic Area 12 categories landscape elements of the area and perimeter distribution distribution is similar to a large area of ??landscape elements have a larger perimeter. The landscape elements of the area, perimeter, and has a number of imbalances in the distribution of the plaque. Among pine landscape of the area and perimeter of the largest water landscape of the area and perimeter of the smallest; conifer landscape has the largest number of patches, landscape garden landscape and water bodies have the least number of plaques. Landscape elements area, perimeter and patch number distribution is no obvious relationship between regularity, mainly with landscape elements related to the degree of fragmentation. In Gushan Scenic Area, each degree of fragmentation of landscape elements were significantly different. Anthropogenic interference with fewer low degree of landscape fragmentation, landscape connectivity is good; while the bamboo forest landscape landscapes and inhabitants to human disturbances intense landscape, relatively high degree of fragmentation. 3, for 2001 and 2007 Gushan Scenic Area landscape pattern changes, the results showed that: 6 years Gushan Scenic Area landscape diversity, dominance and evenness index did not change and other landscape. Gushan Scenic Area remains unchanged overall landscape is still a natural pine forest landscape as a substrate other landscape mosaic of landscape pattern, but the presence of local landscape change: (1) plaque area change analysis showed that: in the area of ??the 12 categories of landscape types, the reduction in the area of ??pine forest landscape type, slash pine, farm and garden, landscape area increases types of coniferous trees, broadleaf forest, coniferous forest, bamboo forest, shrub, residential areas, bare land, which , shrub, broad-leaved forest, coniferous forest landscape types such as increased area larger; (2) patch shape change analysis showed that: 12 categories landscape types MSI index and MPFD index changed slightly, most of the landscape MSI index value and the type of MPFD index values ??showed a decreasing trend; (3) plaque density analysis showed: Residential Landscape Landscape and bamboo plaque density values ??increased more reached 10.68 and 8.72 respectively. Farmland landscape garden landscape and reduce more plaque density values ??were 5.59 and 6.51. These plaques density variation in the landscape types are closely related to human activities; (4) adjacent index distribution and variation analysis showed: pine forest landscape scattered with adjoining largest index, which also shows a pine forest landscape is to study the regional distribution the most widely used type of landscape; residential area adjacent landscape studded with the biggest index change, its value increased from 76.779 in 2001 to 78.727 in 2007, which indicates that residents in six years Landscape tend to disperse more obvious, the study results and field work monitoring results.
