Landscape Health Assessment And Spatial Structure Optimization Of Qingdao City

With the rapid industrialization and urbanization development, urban population growth, resource consumption, environmental degradation; the city lost a large number of natural habitats, urban landscape instability, fragmentation, vulnerability increased, the residents'life quality and health levels declined. The concept of health in landscape assessment is good for coordination of human and environment relationship and achieving ecologically sustainable development. As the leading city of Blue Peninsula Economic Zone, Qingdao's healthy development is of great significance. Evaluating Landscape health of Qingdao City and building the landscape pattern to provide suggestions for ecological construction, while also promoting ecological province of Shandong Province.This paper is based on the landscape ecology theory. It initially constructed a comprehensive urban landscape health assessment index system from the aspects of landscape structure, landscape energy, landscape ecology and ecological resilience. Then make the landscape classification map of Qingdao in combination of remote sensing and GIS technology. Next calculate the indicators of landscape structure, using the landscape analysis software FRAGSTATS3.3.This paper selected landscape index,economic and social indicators,ecological indicators to determine weights using the entropy method and AHP. After the comprehensive evaluation of landscape health of Qingdao city, it analyzed the major limiting factor of landscape health.Entropy method and the AHP are used to determine the index weights. Then use the comprehensive evaluation method to evaluate the landscape health of Qingdao City. And analyze the main limiting factor of landscape health after the calculation of health indicators and limited degree index.The result reflects that Qingdao is in a relatively healthy state, the limiting factor including Shannon diversity index and evenness index of the landscape, landscape fractal dimension index, the proportion of investment in science and education, per capita living space and so on. According to the evaluation results, this paper proposed some optimization measures and the landscape of Qingdao environmental management strategy. Finally, study the landscape spatially structure of Qingdao City. Within the study area, larger than 100 hectares of woodland patches are chosen as landscape ecological protection sources, such as: (1) Laoshan Mountain, this can reduce the external interference, develop biodiversity and also can save Taoist culture color;(2) Jihongtan Reservoir and Taoyuan River. Jihongtan Reservoir is the only regulating reservoir of diversion project. (3) Little Pearl Mountains. Little Pearl Mountains belong to Laoshan Mountains, forming in the Yanshan Period, is the natural barrier of Huangdao area;(4) Fushan Mountain. In addition, the Chengyang White River and Licun River are also within the city's ecological protection scope.And build the cumulative cost distance model to analyze the ecological protection of Qingdao source, landscapes strategic points and important ecological corridor, so as to improve the integrity and continuity of the urban landscape and promote the maintenance of landscape health of Qingdao.
