摘要：近些年经济快速发展使长江经济带出现了一系列的生态环境问题,而生境质量是区域生态环境恢复的关键。林业生态工程的开展使长江经济带植被覆盖度得到有效提升,生态系统质量得到一定程度的改善,遏制了生境质量的下降速度。本研究采用InVEST生境质量模块,设置林业生态工程单一驱动力情景,评估了2000—2015年长江经济带生境质量的时空变化,以及长江流域防护林工程和天然林保护工程对长江经济带生境质量的影响。结果显示:长江经济带生境质量在空间上呈现出东低西高的分布特征,低值区主要分布在长三角北部、江汉平原与四川盆地,云南、江西和浙江平均生境质量指数较高,而林业生态工程的实施对长江经济带生境质量的空间分布没有起到决定性改变。2000—2015年长江经济带生境质量向两极化发展,生境质量中等水平地区逐渐向低水平和高水平转化,整体平均生境质量指数变化不明显。林业生态工程对生境质量产生一定的提升作用,具体表现为进一步提升中高生境质量水平地区的生境质量,但对生境质量水平较低的地区作用不明显。
The rapid economic development in recent years has caused many eco-environmental problems in the Yangtze River Economic Belt.Habitat quality is important for the restoration of the regional eco-environment.The development of forestry ecological projects has substantially increased vegetation coverage in the Yangtze River Economic Belt,improved ecosystem quality,and restrained the decline rate of habitat quality.Here,we evaluated the temporal and spatial variations of habitat quality in the Yangtze River Economic Zone from 2000 to 2015,as well as the impacts of the Yangtze River Shelterbelt Project and the Natural Forest Protection Project on the habitat quality,by applying InVEST module and setting up a single driving force scenario for forestry ecological projects.The results showed that habitat quality of the Yangtze River Economic Belt was lower in the east and higher in the west.The areas with low-level habitat quality were mainly distributed in the northern Yangtze River Delta,Jianghan Plain,and Sichuan Basin,while Yunnan,Jiangxi,and Zhejiang had higher average habitat quality index.The implementation of forestry ecological project did not lead to a decisive change in the spatial distribution of habitat quality in the Yangtze River Economic Belt.From 2000 to 2015,the habitat quality of the Yangtze River Economic Belt was developing towards polarizations.Areas with medium-level habitat quality gradually shifted to low or high level,resulting in no changes of the average habitat quality index.Forestry ecological projects had a certain effect on the improvement of habitat quality,which was specifically manifested in further improving the habitat quality of areas under medium and high levels,but had minor effect on areas with low levels of habitat quality.
