中文摘要:
      洞庭湖区水资源总量较为丰富,但近年来在气候变化以及强人类活动的影响下,水资源短缺问题日益凸显。根据1988-2018年的降水及径流数据,采用趋势及突变分析等方法分析了洞庭湖北部地区降水量和地表水资源量的演变特征。结果表明:洞庭湖北部地区降水量呈先减小后增大的趋势,年际波动增大,荆南“三河”径流量呈显著减少;与 1988-2003年(三峡水库蓄水前)相比,2004-2018年(三峡水库蓄水后)洞庭湖北部地区本地水资源量由38.90×108 m3减少到30.07×108 m3,减小幅度为22.7%;过境水资源量由608.7×108 m3减小到471.4×108 m3,减幅为22.6%;2004-2018年洞庭湖北部地区9、10月的过境水资源量大幅减少,其中10月份减少幅度达45%。
英文摘要:
      The Dongting Lake area is enriched with water resources; however, under the influence of climate change and intense human activities, water resources shortage has become increasingly prominent in recent years. Based on the precipitation and runoff data from 1988 to 2018, the evolution characteristics of precipitation and surface water resources in the north part of Dongting Lake was analyzed using trend and abrupt change analysis methods. The results showed that the precipitation in the north Dongting Lake area showed a trend of decreasing first and then increasing, with an increasing amount of inter-annual fluctuations. The runoff of the “Three Rivers” in Jingnan decreased significantly. Compared with the period of 1988-2003 (before the impoundment of the Three Gorges Reservoir), the amount of local water resources in the north Dongting Lake area from 2004 to 2018 (after the impoundment of the Three Gorges Reservoir) decreased from 3.89×109m3 to 3.01×109m3, a decrease of 22.7%, and the amount of transit water resources decreased from 60.87×109m3 to 47.14×109m3, a decrease of 22.6%. Furthermore, the amount of transit water resources in the north Dongting Lake area from 2004 to 2018 decreased sharply in September and October, with a decrease of 45% in October.
