摘要
目的:探究塔河流域植被覆盖对气候不同因素变化的影响。方法:选取降水量、气温以及相对平均湿度作为气候因子、NDVI作为植被覆盖度指标,使用Sen+Mann-kendall趋势分析方法分析塔河流域植被覆盖对气候变化的影响。结果:塔河流域NDV与气温相关系数为-0.159,与相对平均湿度相关系数为0.158。结论:塔河流域植被覆盖与降水量、相对平均湿度呈现出正相关关系,与气温呈现出负相关关系,且其对降水量的影响较大。
Objective:To explore the impact of vegetation cover on climate changes in the Tahe River Basin.Method:Precipitation,temperature,and relative average humidity were selected as climate factors,and NDVI was used as vegetation coverage index.The Sen+Mann-Kendall trend analysis method was used to analyze the impact of vegetation coverage on climate change in the Tahe River Basin.Result:The correlation coefficient between NDV and temperature in the Tahe River Basin is-0.159,and the correlation coefficient with relative average humidity is 0.158.Conclusion:The vegetation coverage in the Tahe River Basin is positively correlated with precipitation and relative average humidity,negatively correlated with temperature,and has a greater impact on precipitation.
