The Strategy And Way Of Ecological Construction Forestry Research In Gansu

This thesis reviews and analyses the ecological construction of forestry in Gansu, dissects the process of ecological construction, sums up the human environment, social environment, political environment, natural environment, planning and management, organization and implementation, construction method, and technical system of ecological construction, summarizes the successful experience and lessons drew from ecological construction, examines and distinguishes the problems, investigates the feasibility of strategic target of ecological construction, and discusses the measures solving the problems and developing construction quality through utilizing the measure of general conclusion and thought of sustainable development, basic theories of ecological construction and forestry ecological construction, principles of ecology, forestry and ecological control, and data and materials accumulated from the author's working experiences for many years.The author analyses that during the ecological construction of forestry in Gansu for 50 years, there is 12 pieces of experience as following: wide awareness, leaders'attention, adjusting measures to local conditions, measures development, system improvement, combination of ecological construction of forestry and people's production, strict inspection, developing responsibility, combination and operation of all measures, suitable plants in suitable sites, and"three-season"planting. The main lessons are as following: unsuitable trees selection, unsuitable planning, contradictions of forestry and farm grazing, problems occurred in forest rights, and etc. The main problems occurred are as following: low survival and preservation rate, frequent disaster, hard task for present vegetation protection of natural forest, singleness of tree species, lack of key technique of plantation, low management level, lack of financial distribution and technical support.The research result shows that the strategic targets and overall arrangements of the ecological construction of forestry in Gansu are suitable and feasible. Gansu, located in the intersection of three natural regions and three plateaus of the state, is one of major ecological construction provinces of the state and is surrounded by three dresent of Tenggeli, Badanjilin and Kumutage. Meanwhile, Gansu is the important region of accumulating the ecological construction experience of the state. Where the shoe pinches of the ecological construction of forestry in Gansu is the development of ecological construction quality and ecological service.Five strategies are put forward as following: 1, to sum up the experience, lessons and models; 2, to create the good social environment, which includes the awareness of the traditional culture of the state, control of population and development of people's quality, implementation of ecological migration, management development, introduction of social funds, system development; 3, scientific planning, which includes that one is combination of ecological construction of forestry and rural economic development, second is change of traditional management thought and models, third is suitable planning of vegetations, forth is suitable plants in suitable sites, fifth is consideration of historical natural change, and sixth is stability of mixed vegetation;4, to develop the technical contents; 5, to adjust the annual task according to the change of climate, especially the change of precipitation in semi-drought area.
