- [目的]了解近20多年来泾河流域植被时空变化情况,探析气候变化、人类活动对植被变化的影响,为科学评估区域生态环境质量和建设成效提供科学依据。[方法]基于2000—2021年NDVI、气温、降水、人口密度、土地利用数据,采用趋势分析、相关性分析等对泾河流域NDVI的时空变化及其影响因素进行了研究。[结果](1)2000—2021年,泾河流域NDVI呈增加趋势,全区平均增速为0.059/10 a。(2)气温、降水与NDVI总体均呈正相关关系,气候变化有利于植被改善,且降水变化对NDVI的影响大于气温的影响。(3)人口密度变化与NDVI变化趋势呈负相关,流域人口密度的减小有利于植被的恢复和改善。(4)土地利用类型内部变化是NDVI变化的主要原因。NDVI显著减小的主要原因是关中平原耕地NDVI 的减小,而NDVI显著增加的主要原因是草地、林地以及黄土丘陵区、黄土残塬区耕地NDVI的增加。[结论]研究时段内,气候变化对泾河流域植被的改善有积极作用,同时,农业生产技术的提高,生态移民、退耕还林、生态修复等政策的实施是植被覆盖上升的重要因素。
- Abstract:
- [Objective]The aims of this study are to understand the spatiotemporal changes of vegetation in the Jinghe River basin in the past 20 years, to explore the impacts of climate change and human activities on vegetation change, so as to provide scientific basis for assessment of regional eco-environmental quality and construction effectiveness. [Methods]Based on NDVI, temperature, precipitation, population density, land use data from 2000 to 2021, the spatiotemporal variation characteristics of vegetation NDVI and its influencing factors in the Jinghe River basin were studied by using trend analysis and correlation analysis. [Results](1)During the past 22 years, vegetation NDVI in the Jinghe River basin increased significantly, with an average growth rate of 0.059/10 a. Spatially, NDVI in the Guanzhong Plain located in the southern of the study area showed a decreasing trend, while it increased significantly in most of the northern part of the study area.(2)On the interannual scale, temperature and precipitation had a positive correlation with NDVI. Climate change was beneficial to vegetation improvement, and the impact of precipitation on NDVI was greater than that of temperature.(3)The change of population density was negatively correlated with the change of NDVI, which indicated that the decrease of population density was beneficial to the restoration and improvement of vegetation.(4)The internal change of land use type was the main cause of vegetation NDVI change, and the decreasing trend of NDVI in the significant decreasing area was mainly caused by the decreasing of farmland NDVI in Guanzhong Plain, the increasing trend of NDVI was mainly caused by the increase of NDVI in grassland, woodland, loess hilly area and loess remnant plateau. [Conclusion]The Jing River basin is located in semi-arid-semi-humid transition zone, where vegetation cover is greatly affected by climate and human activities. During the study period, climate change had a positive effect on the improvement of vegetation. At the same time, the improvement of agricultural production technology, the implementation of policies such as ecological migration, land conversion and revegetation, and ecological restoration were important factors on the increase of vegetation cover.
