- W3206005993 abstract "Ecological security is an important guarantee for the sustainable development of regional economy and society. We analyzed the change characteristics of fraction vegetation coverage (FVC) and remote sensing ecological index (RSEI) of four irrigated agriculture regions of the Loess Plateau (Yinchuan Plain, Hetao Plain, Fenhe River Valley and Weihe River Plain) based on the remote sensing data from 2000 to 2018. The results showed that the FVC decreased in the study area from 2000 to 2018. The variation trend of FVC differed among the four irrigated agricultural distribution areas. The RSEI of the whole area showed an overall downward trend, the RSEI of Yinchuan Plain (down 0.06) and Weihe River Plain (down 0.07) decreased significantly, and the RSEI of Hetao Plain remained stable. The RSEI of Fenhe River Valley showed an increased trend. The ecological stability of Yinchuan Plain and Fenhe River Valley was relatively low, the ecological environment of Hetao Plain was relatively stable, and the ecological environment of Weihe River Plain continued to degrade. The results were important for regional ecological environment protection and agricultural sustainable development.生态安全是区域经济社会可持续发展的重要保证。本研究基于2000—2018年间的遥感数据,系统分析了黄土高原4个主要灌溉农业分布区(银川平原、河套平原、汾河谷地和渭河平原)植被覆盖度(FVC)和遥感生态指数(RSEI)的变化特征。结果表明: 2000—2018年间,研究区FVC整体呈下降趋势,但4个不同灌溉农业分布区FVC变化趋势各异。研究区RSEI整体呈下降趋势,其中,银川平原和渭河平原的RSEI下降明显,分别下降0.06和0.07,河套平原的RSEI无明显变化,而汾河谷地的RSEI整体呈上升趋势。4个区域中,银川平原、汾河谷地的生态稳定性较差,河套平原的生态环境较稳定,而渭河平原的生态环境持续退化。研究结果对区域生态环境保护和农业可持续发展具有重要意义。." @default.
