The land is a comprehensive resource is the material basis of human survival and development, and environmental conditions, and thus the land problem has always been the basic problems of human society can not be ignored. Land use is not only the most basic human production activities, and socio-economic issues related to human survival and development, and ecological and environmental problems. In this context, Jiaozuo City, land-use change in response to the ecological carrying capacity study has important scientific value and practical significance. In this paper, on the basis of the analysis summarizes the research at home and abroad with the theory of combing, first of Jiaozuo City, from 1998 to 2008, land change data in accordance with, respectively, from the number of land resources, the extent of land use, land-use structure, land use intensity aspect of of Jiaozuo land use changes; Second, principal component analysis of Jiaozuo City carrying capacity of resources, environmental carrying capacity, social influence, ecological elastic force of four subsystems, based on the completion of Jiaozuo City 2000 2008 comprehensive evaluation of the ecological carrying capacity; Finally, the canonical correlation analysis of the relationship between Jiaozuo City, land-use change and ecological carrying capacity. The study and the main results are as follows: (1) Jiaozuo City land use change analysis. This paper analyzes the changes in Jiaozuo City, the amount of land, the extent of land-use, land-use structure and strength. The results show that: the number of aspects, from 1998 to 2008, Jiaozuo City, the number of agricultural land and construction land overall growth, showed a rapid decrease trend unused. The degree of Jiaozuo City Land Use Change Index inflection point in 2002 and 2003, showing a stage of transition. Structure, from 1998 to 2008 information entropy of land use structure in Jiaozuo City first rapid rise after entropy stabilize. Strength, Jiaozuo City, three major class of land-use change intensity index from high in the end turn sort: unused land (-0.43%) gt; agricultural land (0.28%) gt; construction land (0.15%). (2) comprehensive evaluation of the ecological carrying capacity of Jiaozuo City. The analysis and comparison of the commonly used methods of ecological carrying capacity study to select the principal component analysis, combined with the characteristics of the ecological carrying capacity evaluation index system in Jiaozuo City, amending them with SPSS software technology platform, Jiaozuo City, from 2000 to 2008 ecological carrying capacity of each subsystem were calculated and analyzed. The results show that, from the start of 2005, the regional ecological capacity index is positive, showing a rapid recovery in the state, by not carrying the trend can carry. (3) The the Jiaozuo City land use change on the ecological carrying capacity of response analysis. Jiaozuo City, land-use change on the ecological carrying capacity of the presence of positive and negative differences and spatial and temporal differences play a role, the turning point of the ecological carrying capacity of changes in land use change course consistent response to the ecological carrying capacity of Jiaozuo City, land-use change in 2004 The demarcation point occurs characteristics shift. (4) based on the above research, policy recommendations from the land use structure, land use degree of sustainable development in Jiaozuo City.
