Study On The Frames Of Modern Forest System For The Town And Country Integration In The Changsha-Zhuzhou-Xiangtan Area

Ecological environment is a fundamental condition of survival and development for Human being, and is the core and foundation of the sustainable development for region-economy society. Maintaining and building the ecological environment , achieving the sustainable development is one of the elementary policies which is insisted on all the time in the modern construction of our country . In the latest years, with the development of economy , society, culture and technology, the procedure of urbanization is quickened, the problem of ecology and environment is sharpened increasingly , the lopsided contradiction between town and country has been formed, the sustainable development of social economy is blocked seriously.The town and country integration is effectively strategic measures for figuring out the contradiction between town and country and relieving its difference, and make the production factor between town and country exchanged and configured reasonably in certain scope. Forest, as the host of the terrestrial ecosystems, is an important part of regional ecosystem about the town and country integration. At present, the greening in the central and urban region has formed insufficiently the benefit that is able to improve the quality of ecological environment in the town, as a result, Having suburb forest brought into urban ecology-environment construction, and launching the modern forest system on the town and country integration are the efficient line that can enhance the quality of ecological environment in the town.In this paper, urban group made up of Changshas Zhuzhou and Xiangtan is considered as study area, forest ecosystem in the town region ecosystem composed of the integrative ecosystem in the Changsha-Zhuzhou-Xiangtan area is seen as study object, according to the theory of ecosystem and the sustainable developments the principles and methods of forest ecology , urban ecology , regional ecology, landscape ecology are synthesized, the law of ecological balance and the exchanged theory of substance flow, energy flow and information flow between ecosystems are used, computer, GIS, RS and GPRS (3S technology) are used as technological means, the layout of typical forest classification in this area and the ecological service function, ecological environment quality and health assessment of ecosystem for urban group, the ecological safety distribution in the towns the problem of theory and practice in the process of building the forest biosphere of Xiangjiang ecology-economy belt are studied systematically.The results show: (l)It will take on very high theory value and practice sense for accelerating the ecological environment construction between town and country s boosting urban vigor and achieving the sustainable development to launch ecological environment quality assessment in the integrative area between town and country s foundation of management information system s theory base of modern forest system for the town and country integrations ecological service functions adjustment and management of forest layout s study of ecological frame.(2)Pure forest of masson pines half-bred forest of masson pine and broadleaved trees broad-leaved forest are three typical forest species during evolution of forest community. It is distinctly different in maintaining water and solidifying soil for various soil species s soil layer thicknesss surface soil layer thicknesss gradients terrain position of masson pine forest; Half-bred forest of masson pine and broad-leaf has obvious plantation layout and very powerful function in maintaining waters solidifying soil and lasting biodiversity and biological productivityon a large scale, it also has hearty life-force and ecological potential, is turning into evergreen and broad-leaved forest; Artificial forest of Cinnamomum camphora(L.)Presl in the Changsha-Zhuzhou-Xiangtan area has evident function in solidifying carbon dioxide, organisms production , substance circle , improving regional climate , cleaning water quality.(3)Ecological environment quality in the Changsha-Zhuzh...
