Tobacco Growing Regionalization Of Ecological Ring In Qinling Mountains Based On GIS

Soil,climate,topography and other ecological factors affect the overall distribution ofcrops. Tobacco is also a cash crop to meet this rule. Planting and climate, soil and otherecological factors of quality tobacco has a direct relationship,"Chinese tobacco plantingregionalization"(2009) pointed out that growing areas in the upper reaches of the Yangtze, theHuang-Huai-growing areas and the northern tobacco-growing areas in the three primarygrowing areas Shaanxi Province are distributed, while the ring is the Qinling Mountains ofShaanxi Province, the major tobacco growing areas.Qinling ecological smoke ring is the main producing area of Shaanxi Province flue-curedtobacco, flue-cured tobacco acreage reached44.88million mu, accounting for91.23percentof the province’s total acreage. After years of development and changes in the ecologicalenvironment, the national tobacco planting regionalization has not effectively guide the layoutof today’s tobacco production smoke ring Qinling ecological zones. In order to furtherimprove the rational use of resources, and promote the production of tobacco ring Qinlingsustainable development, this study ring meteorological, soil, topography and othertobacco-growing areas in Qinling ecological information is based on the use of modernanalytical techniques to analyze the smoke ring Qinling ecological zones ecologicalcharacteristics, application of GIS technology to achieve ecological suitability fine tobaccoplanting regionalization.In this study, on the collection of rings Tobacco Qinling ecological natural and socialresources, use SWOT analysis method to analyze the current situation of the production oftobacco smoke ring Qinling ecological zones; detailed analysis of the characteristics of theecological environment factor ring Qinling ecological effects of flue-cured Tobacco grown upas well as domestic and foreign high-contrast areas of tobacco, tobacco of Central Qinlingecological field growth of≥10℃accumulated temperature, rainfall and soil nutrients andother features are basically qualified field of high-quality tobacco grown, and some are evenbetter than the domestic other tobacco-growing areas outside; construct the evaluation indexsystem of ecological suitability ring Qinling tOBACCO ecology, ecological completedtobacco tobacco-growing areas, Central Qinling ecological suitability zoning district, the smoke ring Qinling ecological area into the most suitable area, suitable area, less suitable,unsuitable area four types. The layout of the tobacco grown on local conditions, to improvethe quality of tobacco, tobacco Shaanxi enhance the core competitiveness of industrialdevelopment, to increase farmers income has important significance of developing the localeconomy, increase revenue and so on.
