九江市水资源量及其变化趋势分析

水文部门积累了长系列的水文资料，2008年完成了1956-2000年江西省水资源调查评价工作。本文在此基础上，结合近15年水资源调查评价工作，分析了1956-2015年九江市降水的年内分配、年际变化及空间分布特征，进而阐述了九江市60年水资源量的特征和年际变化规律，采用线性趋势回归检验法，利用SPSS软件对九江市水资源量的变化趋势进行分析。结果表明：九江市水资源量由于受到降水时空分布特征的影响，其年际变化较大；历年水资源总量有增加趋势，但趋势不明显。

英文摘要:

Hydrology Department has collected long series of hydrological dates, and finished the investigation and evaluation of Jiangxi province water resource during 1956-2000 in 2008. On this basis, taken the last 15 years of investigation and evaluation of water resource into consideration, the annual distribution, interannual variation and spatial distribution of precipitation in Jiujiang during 1956-2015 are analyzed. The characteristic of water resource quantity in Jiujiang for last 60 years, rules of the annual variation, and the changing trend of water resource quantity of Jiujiang are studied by using of linear trend regression test and SPSS software. The results show that the water resource quantity of Jiujiang was affected by the temporal and spatial distribution characteristics of precipitation, and the interannual variation of water resource is relatively large. Over the years total water resource shows a growth trend, but the trend is not obvious.
