| 中文摘要: |
| 文章运用逐步回归分析方法和GIS 技术，建立了南平市越冬期极端最低气温（Td）和3 个等级冻害（-3℃＜Td≤0℃、-5℃＜Td≤-3℃、Td≤-5℃）发生频次的空间分析模型. 根据主成分分析法确定的政和大白茶冻害区划指标，对南平市政和大白茶种植区进行划分. 结果表明：（1）南平市政和大白茶种植区可区分为微冻害区、轻度冻害区、中度冻害区、重度冻害区；（2）微冻害区分布于武步溪-迪口溪-建溪-高阳溪-吉阳溪-路兹溪-麻溪-富屯溪（顺昌段）-水口寨河-蛟溪以南，轻度冻害区分布于溪东溪-松溪（建瓯段）-梅龙溪-渭田溪-松溪（松溪段）-金峰山-奶娘岗-南浦溪（建阳段）-崇阳溪-云谷山-茂岭岗-麻阳溪-富屯溪（邵武段）-同青溪至微冻害区北界地带，中度冻害区分布于鹫峰山-龙头山-五马并槽-富岭溪-南浦溪（浦城段）-临江溪-武夷山（浦城县与武夷山市交界处）-北溪河-虎鼻岩-葛仙-分水关-狮子岗-杉岭-富屯溪（光泽段）-西溪-金溪至轻度冻害区北界，中度冻害区北界以北为重度冻害区. |
| 英文摘要: |
| With stepwise regression analysis method and GIS technology，spatial analysis model is established for occurrence frequency of the extreme low temperatures（Td）and three frost-damaged grades（-3℃＜Td≤0℃，-5℃＜Td≤-3℃，Td≤-5℃）in the winter period of Nanping. And based on the frost-damaged division indicators obtained in the principal component analysis method, Zhenghe white tea growing areas in Nanping are classified into different areas. The results suggest：（1）Zhenghe white tea plantations in Nanping can be typed into the subtly frost-damaged area，slightly frost-damaged area，moderately frost-damaged area and seriously frost-damaged area．（2）The aforementioned areas respectively refer to the areas to the south of the belt of Wubuxi-Dixikou-Jianxi-Gaoyangxi-Jiyangxi-Luzixi-Maxi-Futunxi（the section in Shunchang）-Shuikouzhai river-Jiaoxi，the areas between the belt of Xidongxi-Songxi（the section in Jianou）-Meilongxi-Weitianxi-Songxi（the section in Songxi）-Jinfeng mountain-Nainianggang-Nanpuxi（the section in Jianyang）-Chongyangxi-Yungushan- Maolinggang-Mayangxi-Futunxi（the section in Shaowu）-Tongqingxi and the Northern boundary to the subtly frost-damaged areas，the areas between the belt of Jiufeng mountain-Longtou mountain-Wumabingcao-Fulingxi-Nanpuxi（the section in Pucheng）-Linjiangxi-Mount Wuyi（the junction of Pucheng County and Wuyishan city）-Beixi river-Hubiyan-Gexian-Fenshuiguan-Shizigang-Shanling-Futunxi（the section in Guangze）-Xixi-Jinxi and the Northern boundary to the slightly frost-damaged areas，and the areas to the north of the Northern boundary to the moderately frost-damaged areas. |
