吉林省东南部山区地方水电年利用小时数对气候变化的响应

The impact of annual using hours of local hydropower in Northeast mountain area of Jilin Province on the climate change

气候变化将使吉林省东部山区温度、降水量呈增加趋势,影响到地方水电站的装机容量利用率。地方水电站对降水量的响应体现为年利用小时数增加,对温度变化的响应体现为春季年利用小时数减少、冬季年利用小时数增加,而春—冬季温差的扩大会导致年利用小时数减少。

climate change will make the temperature and precipitation to increase in the mountains area, the eastern part of Jilin Province, and impact on the capacity utilization rate of the local hydropower station. Local station in response to precipitation for the year reflect the increasing use of the number of hours, to temperature change will reduce the hours during the spring, and increase hours during the winter, and the spring -- winter temperature different will reduce the use of the number of hours.
