摘要
以荔枝种植面积最大的广东、广西为代表,依据自然灾害风险分析原理、历年气候、种植面积和产量资料,分别就华南地区各县荔枝的灾损率、易灾性和防寒抗灾能力进行了分析,并以综合的风险指数为区划指标,对华南地区荔枝寒害风险进行了空间区域分划和分区评述。
Taking Guangdong and Guangxi provinces with the largest litchi-growing areas in China as a representa-
tive, and based on the risk analysis principles of natural disasters, climate, planting area and yield data, the disas-
ter damage rate, vulnerability and cold damage-resisting capacity of the litchi in every county of South China are
analyzed. Cold damage risk zonation of litchi is made using a synthetic risk index as zoning criteria,and the features
of each region are evaluated.
