摘要
利用1951 2000年南阳市降水资料和全国第二次水资源调查评价数据,分析了降水量的年变化趋势及其对水资源的影响,结果表明:南阳市年降水量呈减少趋势,受其影响,水资源量也呈减少趋势。南阳市人均水资源虽在河南省辖市中位居第三,但仍属缺水地区。因此,需要采取综合措施,建设节水型社会,促进经济发展与水资源的协调。
This paper analyzes the annual variation tendency of precipitation and its influence on water resources, according to the precipitation materials of Nanyang during 1951-2000 and the evaluation data of the second countrywide investigation for water resources. The result shows the annual precipitation of Nanyang is reducing, and the quantity of water resources is also reducing with its influence. The average per water resources quantity of Nanyang is the third among all the cities in Henan province, but it still belongs to the district which lacks water. Therefore, the writer suggests that synthetic measures should be adopted and constructs a water--thrifty society to promote the coordination between the economic development and water resources.
