Chengdu Kiwi Fruit Climate Zoning Model Research And The Realization Of Visualization

In the context of global warming, the sustainability of agricultural production has been affected. The impact of climate change on agriculture has been observed in the past 20 years, crop planting systems, and changes in layout. According to these circumstances, under the current conditions, we carry out on the Chengdu kiwifruit climate adaptation research to meet the requirements of planting area, while avoiding blindly expanding the acreage, reduce the resulting negative market price fluctuations.Based on the effect of growth conditions on Chengdu kiwifruit, such as light,temperature and water, this paper analyzes the related requirements needed for the growth of climatic conditions in the area of kiwifruit, and then found out the restriction factors of Kiwifruit growth. On the basis of zoning indexes, using decision tree, we got the Chengdu kiwifruit planting suitability regionalization map.The domestic and foreign GIS technology has been successfully applied to the study of agricultural climate resources, this paper first analyzes the status quo, found out that the agricultural climate resources information system has a very important value,we can not ignore the system in time to explore the role of system. Secondly, under the GIS integrated software development environment, based on the VB development language, the completion of the Chengdu city zoning system of kiwifruit climate was designed and developed, also we designed a humane and practical user interface,developed the system function more perfect and comprehensive; finally, based on the system, combined with the relevant knowledge and technology of mathematical analysis,the climate resources database of Chengdu City Based Geographic and the data of 13 meteorological stations as the data source, the establishment of a special agricultural climate division model, fully reveals the agricultural production of Kiwifruit Spatial distribution of climat resources.In the design of the system is divided into display, based on the use of the operating systemand the third party software, analyze and solve the mixed programming problems, , to make full use of its potential function, effective integration of climate information and data statistical analysis, kiwifruit climate division output function, and realizes the whole system design.
