Analysis Of Yantai's Landscape Pattern

Yantai City lies on the littoral of Shandong province. It is a littoral city of tour resource. With the development of its economy, the Yantai's landscape pattern is changing ceaselessly, which leads to natural ecological progress and sustainable development of environment is enduring fatal threaten. Landscape elements appear to be severely adjusting. Especially Yantai lies on the coast of littoral and mountain is at the back of it. Plain area is very little. It has particular landscape pattern. The change in Yantai's landscape pattern will influence its sustainable development. Especially with the development of its economy, the change in landscape pattern makes against people's living. A case in point, with the intensely increasing and correspondent people's living, producing soil rapidly enlarging, the cell type of woodland, grassplot, water area and farmland that maintain natural ecology and environment in landscape pattern not only is reducing, but also will be continuingly reducing, which lead to the simplification of the whole area's ecology and environment. The city's greenbelt is ceaselessly reducing. The resource of biology diversity is fatally damaging, which reduce the landscape stability. The absorbing ability to various influences of the environment is falling. Environment pollution is increasingly aggravating. Because soil coordinate destroy the vegetation of the surface in the area, bareness of soil and a lot of soil leave unused long time, soil and water erosion is increasingly broadening. Human activities make the natural elements extremely shrink. The only living natural and half-natural landscape elements are intensely divided, which lead to the increase of the landscape fragment. And with the increase of the city's landscape fragment, landscape expedite is apparently reducing. The abundantly reduce of the natural landscape element makes the natural landscape element live only through city's greenbelt. and its distribution in spatial is very equilibrium. Because the structure of the greenbelt is sometimes single, its cover is sparse and lacks arrangement. It is difficult for it to fulfil the ecological function.Landscape ecology is a new intersectional subject. The reciprocity between landscape pattern and ecological process is its orientation. As a subject, landscape ecology is formed in the sixties of twentieth century. Though different scholars describe it differently, landscape pattern is emphasized for them. The basic elements of landscape pattern include patch, corridor and matrix. The pattern of their configuration of time and space is landscape structure. Patch's spatial distribution is named landscape pattern. Different landscape patterns have large difference to theindividual, community and ecology system. So quantitative analysis to the landscape pattern is aninimportant content in landscape ecology.The change in landscape pattern of Yantai is wholly analyzed using principles of landscape ecology. Yantai's landscape structure is simply analyzed according to the principles of landscape ecology. And Yantai's main landscape process is also analyzed. Yantai's landscape pattern is analyzed using quantitative analysis of landscape ecology.The main content include: Yantai's landscape is divided into seven types, including town an rural constructing land, woodland, orchard, vegetable land, irritable land, dry land and water area. Then spatial data and attribute data of Yantai's different landscapes of two times are picked up using remote sense information model according to its image characters in the digital remote sensed image and definite disposal manner. .And then spatial data and attribute data are systemic analyzed using GIS software. Yantai's attribute data of different landscapes is analyzed through different models using quantitative measures in landscape ecology, including contrast analysis to different landscape patterns. For example, patch's size, shape, edge ratio and correlation analysis of different landscape patterns, model analysis of landscape patterns,...
