基于GIS空间分析的广东省油茶种植适宜性评价

为加强广东省油茶种植区域布局合理性，提高油茶产业发展的可控性，以广东省油茶产业为研究对象，在利用气候因子、土壤因子、地形因子、数字高程模型（DEM）、科技支撑及育苗情况等数据分析的基础上，采用层次分析法对广东省油茶产业发展规划布局进行GIS适宜性评价． 结果表明：河源市、梅州市、清远市、韶关市、云浮市的西部、茂名市的北部、肇庆市的东部、阳春市及阳西县等地综合条件好，适合油茶产业的推广和开发．

Suitability Evaluation of Camellia oleifera Planting Based on GIS Spatial Analysis in Guangdong Province

To strengthen the rationality of spatial distribution of Camellia oleifera planting area and promote the controllability of C.oleifera industry development in Guangdong province, based on GIS, data status on climatic factors, soil factors, terrain factors,digital elevation model (DEM), scientific support and seedlings cultivation collected from C.oleifera planting area in Guangdong province, the suitability of spatial distribution of C.oleifera industry in Guangdong province is evaluated by analytic hierarchy process. Results show that some regions are found to have good comprehensive conditions, such as Heyuan city, Meizhou city, Qingyuan city, Shaoguan city, western regions of Yunfu city, northern regions of Maoming city, Yangchun city, eastern regions of Zhaoqing city, Yangxi city, where are suitable for promotion and development of C.oleifera industry.
