| 摘 要： | 参照《生态质量气象评价规范(试行)》标准,以2008—2013年遥感晴空数据及相关气象、统计、调查等资料为数据源,对江西省生态环境状况进行气象评价,并对其动态变化进行分析。结果表明,2008—2013年,江西省生态环境状况整体处于良好水平,且生态质量逐年略有提升。其中,1)江西省植被覆盖度整体较高,并呈小幅上升趋势;2)湿润指数亦呈现小幅上升趋势,并且江西省降水随季节分布不均,春季湿润指数值平均最大;3)水体密度指数及土地退化指数较稳定,但存在季节变化;4)灾害指数随年度受灾程度不同有较大起伏,夏季是江西省遭受气象灾害较为频繁的季度。

| Abstract: | Referring to Standard of Meteorological Evaluation of Ecological Quality （Trial）, the meteorological evaluation of ecological environmental conditions in Jiangxi province was carried out by using the clear air remote sensing data, meteorological data and survey data from 2008 to 2013. The results indicate that ecological quality in Jiangxi province is at good level, with slightly increases from 2008 to 2013. （1） The vegetation coverage in Jiangxi province is higher as a whole, and showed a slight increase trend. （2） The moisture index presents a slight increase trend, with a maximum value in spring. The seasonal precipitation presents uniform distribution. （3） The water density index and land deterioration index are stable, but change seasonally. （4） The disaster index changes with the yearly meteorological disasters. |
