广西荔枝精细化农业气候区划与应用研究

摘要：本文在研究广西荔枝生产现状和生态适宜性基础上，密切结合广西荔枝生产实际，筛选出广西荔枝精细化农业气候区划指标，运用广西90个气象站点1971-2000年的气候资料和台站地理信息，1：25 万地形数据, 建立了区划指标的空间分析模，按1 km ×1 km细网格对区划指标进行了小网格推算，采用GIS技术和打分法，在精细化农业气候区划系统平台上，将广西荔枝进行了精细化农业气候区划，分为最适宜区、适宜区、次适宜区和不适宜区四大区域，在此基础上，对照广西荔枝生产现状，进行了农业生产上科学布局与生产结构调整的对策措施研究，旨在为农业生产提供科学依据。

Study on Precise Comprehensive Agricultural Climate Regional Planning and Application of Leechee in Guangxi

Study on Precise Comprehensive Agricultural Climate Regional Planning and Application of Leechee in Guangxi Guo Shumin1, Chen Yinjun1, Su Yongxiu2, Zhong Shiquan2, Li Zheng2 (1Institute of Agricultural Resource and Regional Planning, CAAS, Beijing 100081; 2Guangxi Meteorological Disaster Mitigation Institute, Nanning 530022) Abstruct:The paper was studied the current status and ecological suitability of Guangxi leechee combined closely with the production reality of Guangxi leechee production and be selected the index on Study on Precise Comprehensive Agricultural Climate Regional Planning of Guangxi leechee Based on the geographic information and climate data of 90 meteorological stations in Guangxi from 1971 to 2000, the climatic models in grids were established by using the principles of Geographical Information System and method of weighting on the Precise Comprehensive Agricultural Climate Regional Planning method and the Guangxi leechee production area be divided into most feasible area and feasible area and next to feasible area and out of feasible area with Study on Precise Comprehensive Agricultural Climate Regional Planning system and be studied the scientific layout and structural adjustment of agricultural production compare to the current production situation of Guangxi leechee and the aim is that provide with scientific basis of Guangxi leechee production.
