- 摘要:
- 渭河是黄河第一大支流和主要输沙源之一,渭河流域涵盖黄土高原及秦岭地区,跨越不同的气候带且生态环境相对脆弱。因此,对其流域植被覆盖情况及气候响应分析具有重要研究意义。基于MODIS-NDVI数据,结合像元二分法模型计算植被覆盖度,利用趋势分析、Hurst指数进行渭河流域2000—2019年植被覆盖度的空间演变特征及变化趋势分析。结合渭河流域气象数据,利用偏相关分析、Mann-Kendall检验进行气候因子对植被覆盖度的影响分析。结果表明:(1)渭河流域植被覆盖度在空间域上表现为陕北地区及西北宁夏甘肃地区植被覆盖度较低,渭河流域南部秦岭一带及泾河、洛河一带植被覆盖度相对较高,流域整体在空间域上呈现为由东南向西北逐渐递减的趋势;(2)2000—2019年渭河流域植被覆盖度整体呈上升趋势,上升速率为0.095/10 a,其中在渭河干流中下游城市较密集区植被覆盖度有显著性下降;(3)渭河流域植被覆盖度未来变化趋势表现为流域整体呈现进一步改善趋势(面积占93.36%),其中沿渭河中下游城市密集地区植被覆盖度未来变化趋势呈现持续退化趋势(面积占6.64%);(4)近40年来,渭河流域气温呈显著性上升趋势,上升速率为0.42℃/10 a,降水呈现缓慢增加趋势,渭河流域降水、气温对植被覆盖度的相关性影响存在明显的地域特征,且对植被覆盖度影响的关联性并不显著,研究结果可为渭河流域生态建设及水土保持工作提供参考意义。
- Abstract:
- The Weihe River is one of the largest tributaries and main sources of sediment transport in the Yellow River,which covers the Loess Plateau and Qinling region,spans different climatic zones and has a relatively fragile ecological environment. Therefore,it is of great significance to analyze vegetation cover and climate response in this basin. Based on MODIS-NDVI data,we calculated vegetation cover by combining the binary model,and used trend analysis and Hurst index to analyze the spatial evolution characteristics and trends of vegetation cover in the Weihe River Basin from 2000 to 2019. The influence of climate factors on vegetation cover was analyzed by using partial correlation analysis and Mann-Kendall test and combining with the meteorological data of the Weihe River Basin. The results show that:(1)the vegetation cover of the Weihe River Basin showed the low level in the northern Shaanxi region and the northwest Ningxia and Gansu area,the relatively high level in the Qinling area and the Jinghe River and Luohe River areas in the southern part of the Weihe River basin,and presented the decreasing trend from southeast towards the northwest in the whole basin;(2)the vegetation cover of the Weihe River basin had risen overall from 2000 to 2019 with the increase rate of 0.095/decade,the vegetation cover significantly decreased in the regions with the more dense urban areas in the middle and lower reaches of the main stream of the Weihe River;(3)the trend of future changes in vegetation cover in the Weihe River basin showed the further improvement trend in the basin as a whole(area ratio 93.36%),the future trend of vegetation cover in regions with the dense urban areasalong the middle and lower reaches of the Weihe River showed a trend of continuous degradation(area ratio 6.64%);(4)in the past 40 years,the temperature of the Weihe River Basin had shown a significant upward trend with the increase rate of 0.42 ℃/decade,and the precipitation showed a slow increase trend; the correlation between temperature and vegetation cover had obvious regional characteristics,and the correlation of vegetation cover was not significant. The results of the study can provide reference significance for ecological construction and soil and water conservation in the Weihe River Basin.
