盘州市红豆杉保护区气候生态特征及分析

Climate Ecological Characteristics and Analysis of the Taxus chinensis Nature Reserve in Panzhou City of Guizhou Province

摘要: 本文通过对盘州市红豆杉自然保护区气候生态资源的科学考察与分析得到：该区年日照时数1453~1704 h之间，年日照百分率为33%~39%之间，年太阳总辐射为4125.7 mJ/m²~4408.8 mJ/m²之间，是贵州省内日照和太阳辐射较多且各月差异较小地区之一。年平均气温在9.1˚C~17.3˚C之间，年极端最高气温29.2˚C~36.7˚C之间，年极端最低温0.6˚C~−18.2˚C。日均温≥10˚C的持续日数在118~309 d之间，稳定高于10˚C的积温在1451.4~6002.1˚C-d之间；年降水量为1200 mm~1400 mm，保护区主体区域属北亚热带高原湿润季风气候并有干、湿季明显的云南高原气候特征。

Abstract: After the short-term climate ecological resources science survey and datum analyses, the results are as follows: At the Taxus chinensis Nature Reserve in Panzhou City, annual sunshine duration is between 1453~1704 h, annual percentage of sunshine is between 33%~39%, annual amount of so-lar radiation is between 4125.7~4408.8 MJ/m², making it one of the regions with more sunshine and solar radiation and small monthly difference in Guizhou province. Besides, its annual mean temperature is between 9.1˚C~17.3˚C, extreme maximum temperature is between 29.2˚C~36.7˚C, extreme low temperature is between 0.6˚C~−18.2˚C, ≥10˚C continued days is between 118~309 d, ≥10˚C accumulated temperature is between 1451.4˚C~6002.1˚C-d, and annual precipitation is be-tween 1200 mm~1400 mm. It is belongs to the north subtropical humid monsoon climate with Yunnan plateau climate characteristics of significantly dry and wet season.
