A Study On Urban Landscape Ecological Planning

Many cities face a series of so-called 'city diseases' such as traffic jam, housing problems and environmental pollution as economy has developed and cities have expanded rapidly. They produce because the function of urban eco-economics system is lessened resulted from the unreasonable ecological position of landscape and the disorder inner elements of urban landscape. Man must use a new idea to analyze, plan and construct city and use dynamic and mutual consequence to analyze city's development. So, urban landscape eco-planning becomes a focus in many countries and districts.Based on the theories of urban geography, landscape ecology, city plan, the dissertation analyzed and researched Lanzhou city's ecological planning.The thesis is consists of six sections, among which the fourth and fifth are themajor body. In the first section, I put forward the specific destination and significance of the thesis, technological syllabus used and scientific problems to be solved. In the second section, I discussed urban landscape ecological planning's concept, content, principles, and goal. The third gives the theories and methods of city ecological planning and review the past history and present tendency. The fourth consists of two sections: (1)1 use five factors (annual air temperature, soil pollution, comparatively humidity, wind speed and environment pollution ) to analyze the Lanzhou city's ecology environment change since 1949. It concludes that Lanzhou city's ecology environment has become worse. (2) Based on the model of urban landscape ecology evaluation, I use AHP (Analytical Hierarchy Process) method to evaluate Lanzhou city's landscape ecology. We can get the conclusion that Lanzhou city's landscape ecology is worse (scorn 42.039) than the country's cities average (scorn 60). It means that Lanzhou city's ecological environment is not allow optimize and stands back list in China. Based on the content of urban landscape ecological planning, combining Lanzhou city's practicality, the fifth departs Lanzhou city into four parts. They are the south mountains and the North Mountains, the yellow river banks, eco-greenbelt andlandscape function sections. According to respective characteristic and their eco-riche in the whole eco-system, I give them specialist plans. Finally, results of this thesis are synthesized, questions to be explored in the future are raised and expectation on this research fields is systematically presented.
