Water And Land Resources Carrying Capacity Assessment Of Huanan

Human survival and development of land and water resources are an integral part of the social process of natural elements, but also the agricultural production process of an important resource, since ancient times, humans have any production activity without the support of land and water resources. Land resources are all things to survive this, and the water is the source of life, the two are interdependent and mutual restraint. In the study of agriculture should be both as an organic whole to study, in order to better carry out its functions. Huanan County as the country's grain production base, which undertakes the important task of the food supply, but due to the county's surrounding cities affected by the radiation, and traffic conditions, the development of early history, while its water supply and demand benefits sharp mouth, has become an important factor for economic and social development in the county, one of [66]. Therefore, to explore the land and water resources Huanan coupling is balanced, the elements of time and space on the match, studies on water, soil resource use patterns in both strength and coupling relationships will help local sustainable use of land and water resources and effective protection of the environment.This study is a basic work on the sustainable use of regional land and water resources, based on the theoretical basis of inner balance between water, soil resources both to the status quo of land and water resources utilization as a time entry point, the use of remote sensing data and DEM data and other basic data source for GIS and remote sensing data as the basis for the study of land resources to research, the number of changes in the structure of water resources, and land and water resources development and utilization status of the case, based on the analysis results of soil and water resources in the study area the problems; and index system, index weight, carrying capacity of the land and water resources in the study area were evaluated, and the bearing capacity of soil and water resources in the study area and study area, the coupling of both land and water resources analysis, and ultimately concluded that evaluation of Land and Water Resources Carrying Capacity As a result, and the study area was divided into three grades according to the results area. The main conclusions are as follows:(1) Comprehensive carrying capacity to analyze the situation of soil and water resources, decreased from to grade level representatives of regional land and water resources carrying. ? ?Get Huanan County township land and water resources carrying capacity is the camel kidneys grade ?town; ?level of the stone town, the Big Eight waves Township, Meng Gang; ? grade for Ming Yi Township, Jinsha Township, pear township; ?level of Huanan town, home town of Yan, soil Longshan.(2) Coupling of land and water resources were analyzed. The resulting index will be based on Huanan County 10 administrative villages and towns into water and soil coupling advantages zone, water and soil coupling good area, water and soil coupling balance area, soil and water coupling inferior zone four grades, on the whole, Huanan County township land and water resources presents Coupling North Central Soil and Water Resources coordination superior coupling characteristics of the Southwest, where Longshan town, the town of the town of birch and coordination of land and water resources coupled southern Meng Gang comparative advantage.(3) Of land and water resources carrying capacity evaluation results of the study area were analyzed and divided three regions grades. Meng Gang, camel kidney town, stone town, region posed by the Big Eight waves Township, is the area of land and water resources utilization capacity advantage, whether it is integrated in the region carrying capacity of land and water resources, or the coupling of water and land resources are all excellent within the county the large area. Sands Township, Longshan soil, pear Township, Ming Yi Township area is composed of water and soil resources utilization capacity balance area, the synthetic capacity of the regional land and water resources, land and water resources belong to the coupling of the equilibrium state in the county within the region. Huanan town and home town Yan as soil and water resources utilization capacity saturation region, such Land and Water Resources Carrying Capacity in the lowest level, within the county only in barely stage, the future development of this area, we must pay attention to the coordination of various types natural resources, and control the increase of production and life to bring pressure on natural resources, should continue to expand production and life, should maintain the status quo.
