Abstract


Land the terrestrial ecosystems carrier, is the basis of human survival and development, as the population continues to grow, the irrational development of resources and the continued deterioration of the ecological environment, human activity has made the global ecosystem has been unprecedented impact and destruction, ecosystem services is rapidly declining, even a threat to the ecological basis for sustainable human development. China has a vast natural conditions, there is a big difference, and therefore should be targeted land typical areas of sustainable land use study. Land ecological zoning for the sustainable development of human society, there is an urgent need to study more realistic zoning from an ecological point of sustainable use strategy to explore the land system, to provide a scientific basis for socio-economic development of decision-making, in order to achieve sustainable development. This paper described the course of development and the need for ecological zoning, to develop a suitable the Shangyi county land ecological construction and protection zoning principle of the Shangyi County, Hebei Province, the ecological state of the environment and land use status. And three types of indicators of a class of ecosystem services, ecological environment, land resources utilization class, composed of index system of land ecological construction and protection zoning, the variation coefficient method to determine the index weight, the spss clustering partition and other technical means Shangyi County science land ecological construction and protection zoning. Zoning principles and technical support, mainly to do the following: 1 Land Use Survey and Analysis: research on the basis of the site visits, visits to relevant departments to collect data excel and spss technical support, data processing, analysis of land use status quo, the status quo of ecological environment and problems were analyzed on the basis to understand the the Shangyi County natural environmental conditions, economic conditions. Land ecological zoning. To select ecosystem service categories of indicators, including the value of the intensity of arable land Corner intensity value of the services, the service value of the intensity of the woodland, grassland service value of strength, the waters of the service value of strength, service value of unused land strength; ecological environment class indicators include landscape deviation, forest cover, resource indicators include land reclamation rate, the rate of construction land, the establishment of the index system. According to the Shangyi county land ecological construction and protection zoning principle the Shangyi County land system is divided into five categories of ecological construction and protected areas: forestry, animal husbandry ecological coordination area of ??low mountains, mountain, mine ecological environment protection restoration areas, flat dam vegetable industry in ecological protection areas, ecologically sensitive areas of urban land, the high plains of the ecological agriculture and animal husbandry, the built-up areas. Land ecological construction and protection of the basic situation and problems, analysis and to propose effective ecological construction and protection measures conducive to the sustainable use of land. Land-ecological construction and protection to seek the Shangyi county land ecological zone construction and protection strategies: rational coordination of agriculture, forestry, animal husbandry and relationships, do a good job in the construction of ecological agriculture; closed forest and grass to promote natural vegetation recovery, increase protection of natural forests: balance herders protect the relationship between forestry, animal husbandry; strengthen the development of mineral resources management to promote \to strengthen grassland protection the grass efforts, development of ecological animal husbandry; vigorously growing artificial pasture; adjustment of agricultural structure, optimization of land use structure and layout; development of cultural tourism resources.
