Since the 1980s,the level of urbanization development in China has been rapidly increasing.At this stage,the urbanization rate has exceeded 59.58%,but there is still a gap between the target of 70%.It is expected that the next decade will be a golden period of development.At the same time,however,China's development and utilization of land resources has always adopted a relatively extensive mode of operation.The “expansion of large cakes” type of urban expansion has increased the intensity of land development and utilization,affected the balance of urban ecosystems,and led to urban ecological security.Precarious.The urban central city is the artificial construction environment with the strongest land development intensity,the highest intensive degree and the best social and economic benefits within the urban area.The level of ecological security will inevitably affect the overall ecological environment of the city.In view of this,this paper takes Shangluo downtown area as the research object,discusses the land use development and its existing problems of ecological security,discusses its land use optimization allocation strategy,guides the rational expansion of Shangluo downtown area,eases urban construction and ecological protection.The contradiction has an important guiding role.Based on the understanding of the basic content of urban ecological security and the research progress at home and abroad,this paper analyzes the dialectical relationship between urban land use and ecological security,and constructs an ecological safety evaluation index system suitable for the urban area of downtown Shangluo,and applies the analytic hierarchy process.The mathematical method such as the grey correlation analysis method is used to calculate the comprehensive safety value and the correlation value of the ecological security of the urban area in the downtown area of Shangluo,and to explore the relationship between the land use and the ecological security index factors in the central city.The land use structure optimization plan;on this basis,the spatial syntax is used to simulate the impact of different spatial layouts of urban land with high ecological security on the urban ecological security,and the spatial optimization plan for the urban land use is proposed.Combining the quantitative structure optimization results with the spatial positioning optimization results,the comprehensive theoretical scheme of land use optimization in the downtown area of Shangluo is proposed,which is helpful to optimize the ecological security of the land in the downtown area of Shangluo.In the land use optimization technology and implementation strategy Other similar cities face can be certain reference value.This paper explores from the urban land use planning,the ecological security construction of the main functional land and the ecological security maintenance management of urban land.It proposes how to further and stably guarantee the ecological security of the downtown area of Shangluo.In order to achieve the all-round optimization of the ecological security of the urban area in the central city,it is intended to provide a reliable foundation and guarantee for the ecological sustainable development of the land use in the downtown area of Shangluo,and provide a scientific guidance for the ecological security maintenance and planning and construction of ecologically sensitive areas.
