摘要
研究了处于半干旱区的六盘山自然保护区不同区域植被生长与气候条件之间的关系。研究结果显示:六盘山自然保护区近40年来7～9月是一年中降水最多的时期,11月～次年2月平均月降水量在20 mm以下。近10年间3～6月相对湿度大减。这些因素使得六盘山植被区仅在六盘山和南区的阴湿区有较好植被保存,而中北部近于祼地;夏季在生长旺盛季,雨水充沛,温度适宜,森林和草原以及种植区的植被生长最好;秋季植被首先从北部退化,六盘山及东侧附近植被的季节性退化比西侧要晚。
The paper studied the relationship between vegetation growth and climatic change in the different regions of the Liupan Mountain Natural Reserve,which is located in the semiarid area.The research results showed that the precipitation from July to September in the Liupan Mountain Natural Reserve was the most in each year of the past 40 years,and the monthly average precipitation from November to February of the next year was below 20 mm.The monthly average relative humidity from March to June has largely dec...
