摘要
利用遥感资料和文献,研究艾比湖湖面面积的年际和月际变化。利用最小二乘法求参数,进行线性回归,寻求湖面变化和降水因子的相关性,得出降水量和湖面面积的相关系数为0.706 43,经显著性检验,并用大量的数据及事实分析了湖面面积和其他自然因素及人类活动因子的相关性。根据以上研究可以大致预测艾比湖湖面的变化趋势,为决策层制定防治对策提供科学依据。
In this paper, the annual and monthly variation of area of the Ebinur Lake in Xinjiang is researched based on the remote sensing information and references. The change of area of the Ebinur Lake is qualitatively and quantitatively analyzed, the least-squares procedure is used to carry out the linear regression so as to search the correlation between the change of area of the Ebinur Lake and precipitation. The results show that the correlation coefficient between area of the Ebinur Lake and precipitation is 0. 706 43, and the significance test reveals that there is a significant positive correlation between the annual precipitation and the Ehinur Lake area. The correlations between the Ebinur Lake area and the natural factors and human activities are analyzed based on large numbers of data and facts. On which the change trend of the Ebinur Lake area is roughly predicted. The study results provide the scientific basis for the further research and working out the measures for controlling the reduction of the Ebinur Lake area.
