In the course of human land use,conflict and cooperation is as the two sides of a coin,their relationship is the unity of opposites.Uncontrolled have a negative impact on regional sustainable development,and moderate conflicts can also facilitate the integration of regional land resources.Therefore,the quantitative evaluation of land use conflict intensity and its controllability,and the quickly identify of."hot spots" and "sensitive areas" of conflic,are very important for The land us-e zoning control,the quantity structure and spatial layout of various types of land and the ecologi-cal environment protectionWith the improvement of economic and social and the legal system,human beings pay more attention to the difference of social,economic and ecological benefits brought by different land ty-pes.The land use conflicts characterized by property rights are decreasing,the conflicts character-istics of the functional conflict is increasing,the most prominent of which is the social and econ-omic functions and ecological protection between the contradictions,especially in some rapid urb-anization of urban agglomerations,urban construction land rapid and disorderly expansion have posed a serious threat on the preservation of ecological land quantity and structural integrity.In this paper,the spatial conflict model of land use is constructed based on ecological secur-ity,which is based on the combination of PSR model and landscape ecological risk assessment m-odel,from the perspective of geography pattern and ecological coupling.Taking the remote sens-ing data of 1987,1995,2000,2005 and 2011 in Wuhan city circle as an example,this study analy-szes the pressure(source)of the land use system,the internal structure of the system(risk recep-tor),th response Land use system to ecological risk(risk effect),and calculates the land use spa-tial conflict comprehensive index.The results show:The spatial conflict level of land use in Wuhan city circle is in the basic controllable state in t-he study period,and the proportion of general conflict and mild conflict is more than 70%.The h-igh value area is concentrated in the area where the land of construction is expanding rapidly and the ecological fragile areas;conflict low-value areas are mainly concentrated In the remote areas where the economy is less developed and the land type is single;the randomness of the index is decreasing and the aggregation is increasing,especially in the later period.And the spatial charac-teristics and quantitative characteristics of comprehensive in the time dimension is:stabilty to br-eak the stability to stability to break the stability;in 2007,the concept of Wuhan city circle is offi-ceeially formed,which have an importan impact on conflict features that "process-pattern-levels",and played a certain role intensified.
