摘要
对贵定县岩下乡大鲵自然保护区气候生态资源进行了科学考察,发现该区年日照数为1027.5~1158.6h,年日照百分率为23%26%,年大阳总辐射为3435.0—3667.8MJ/m^2;年均温为14.5℃左右,日均温≥10℃持续日数约为229.0d,≥10℃积温约为4433.3℃·d;年降雨量为1142.9~1474.3mm。该区属北亚热带高原湿润季风气候,石山林立,溶洞遍布,洞内水质清澈,是野生大鲵的天然小生境,具有水资源涵养保护价值、大鲵自然保护价值和自然景观游览价值。
Climat/c ecological resources of nature reserve for giant salamanders in Yanxia Area of Guiding County were observed. Annual sun- shine duration was 1 027.5 -1 158.6 h, annual percentage of sunshine was 23% -26% , annual amount of solar radiation was 3 435.0 - 3 667.8 MJ/m^2. Annual mean temperature was about 14.5 ℃, 〉/10 ℃ continued days was about 229.0 d, /〉 10 ℃ accumulated temperature was about 4 433.3 ℃ · d. Annual precipitation was 1 142.9 - 1 474.3 mm. The climate in the area was the north subtropical zone plateau moist monsoon climate. Rocky mountains in the area stood in great numbers. The karst cave was found everywhere.
