摘  要：
在收集整理磴口县 1970— 2 0 0 0年风沙天气资料和 1977— 2 0 0 0年防护林建设相关资料的基础上 ,按照“三北”防护林工程建设的年限划分标准 ,将上述 31年风沙天气资料划分为 4个阶段 ,分别为建设工程前 8年、一期工程 8年、二期工程 10年和三期工程 5年。对不同阶段的风沙天气资料进行方差分析和F检验 ,证明 4个阶段的数据有极显著的差异 ;对扬沙日数和沙尘暴日数与大风日数比值的分析 ,充分显示出乌兰布和沙漠东北缘 4个阶段防护林体系生态防护作用存在着较大的差异 ,说明整体防护功能在不断提高。回归分析表明 ,风沙天气指标 (年均大风日数、扬沙日数和沙尘暴日数 )与防护林指标 (防护林面积、防护林林木蓄积量 )存在着显著的线性关系。

摘  要：
The sand-wind weather data from 1970 to 2000 and the protection forest system construction relative of data from 1977 to 2000 of the Dengkou County had been collected. According to the fixed number of years of protection the “Three-North” protecting forest construction, the sand-wind climate data was divided into 4 periods, construction prophase (8 years), the first period (8 years), the second period (10 years) and the third period (5 years). The statistics results of coefficience analysis and F-statistics suggested that the data of different periods had evident differences. Analyzing the ratio of the elevating sand days and the dust storm days with strong wind days, it showed that the 4 periods protection forest system had marked difference in ecological protective effect on the northeast edge of Wulanbuhe Desert, and the total protective function was increasing gradually. The correlation regression showed that they had notable linear correlation relationship between the sand-wind Weather indexes (strong wind days per year, the elevating sand days and the dust storm days) and protection forest indexes (protection forest area, protection forest volume).
