Eco-geographical Regionalization Of Fujian Province And Its Response To Climate

Eco-geographical is a geographic space for the partition, based of the type of regional ecosystem, environmental sensitivity, the importance of ecosystem services and the processes stressed by the ecosystem and so on. It can not only reflect the temperature, moisture, and biological environment of the integrated area, but also reflect the effects of human activities on environment. It is the macro-regional framework to understand the ecological environment, and it is also the basis of managing the ecological environment. It provides the basis and prerequisite to the regional management, ecological environment.With the principal component analysis of SPSS16.0, it can get two principal components from the sunshine duration, precipitation, annual temperature, January temperature and July average temperature, evaporation, average wind speed, windy days, relative humidity, frost days and accumulated temperature, etc. 11 climate index of 67 counties in Fujian province. With the two principal components, there are two ways to analysis, one way is to use K means method, and another is to use the improved simplex method based on projection pursuit method. It is clearly that the modified projection pursuit technique is rapid and precise.In recent years, human activities produce a lot of greenhouse gas emissions and global warming trending is more obvious. The changes in the climate system are also exacerbated by the process. The article simulate the change of water and heat of Fujian province under the GISS, GFDL and UKMO three models, that is to say, simulating the affection to eco-geographical regionalization of Fujian province when the CO2 concentration is doubled the value of all the natural target. First of all, based on the original natural climate indicators of 67 counties and cities under the Fujian Province, it can get a linear regression of all the natural temperature and moisture indicators and the correlation coefficient, and then calculating the natural target when the CO2 concentration is doubled the value, at last, using the modified projection pursuit technique to analyze the results. The results show that under the three models, the geographical division of the Fujian Province has little effect.In this paper, integrated the natural environment, natural resources, social development and economic development of the 24 indicators in 67 counties and cities of Fujian Province, using of first principal component analysis with SPSS16.0, get the value of the five principal components, then calculate the value of the five principal components analysis with the modified projection pursuit technique. Based on the findings, combined with the ecological zoning map of Fujian Province, topography, climate, soil, zoning plan and other comparative analysis of the qualitative and quantitative analysis, the Fujian province is divided into six geographical regions, and proposed a comprehensive regulation of various regional economic development programs and the main direction for the ecological environment in Fujian province and the rapid economic development to provide a scientific basis.Fujian Province is the heart of Economic Zone. By analyzed the indicators of eco-geographical of Fujian province, based on eco-geographical regionalization of Fujian province, it can find the problems of the West Coast Economic Zone. That problems are the economic development in the west side of the economy area is more stronger that that in the inland city. But the coastal cities in the city's division of functions is not clear enough. For the above, the coastal cities need to optimize the industrial structure, a clear division of urban functions, optimizing the rational allocation of resources, to strengthen industrial cooperation. Inland cities need great efforts to strengthen infrastructure construction, improve the investment environment.
