一、水文地质站的目的与任务本站位于长江下游南京市区一级阶地上。区域内无论是—级阶地,抑二级三级阶地,在岩性及地质结构上均存在很多共同之点,因而它们的水文地质条件也存在着某些相似。江淮丘陵区域一级阶地虽然大部分都巳开墾,然而此其面积更广大的二级三级阶地,由于缺乏水源,大部分为荒芜之地或旱作地,产量受到—定限制,所以目前随着人民公社化后,关于在新墾荒地上灌溉,及旱改水问题,均提出很多要求我们
First, the purpose and mission of hydrogeological station This site is located in the lower reaches of the Yangtze River in Nanjing urban terraces. There are many similarities in lithology and geological structure in both the terraced and third-order terraces in the region, and their hydrogeological conditions also have some similarities. Although most of the first-level terraces in the Jianghuai hilly region have been reclaimed, the second-third terraces of this larger area are subject to a limited production due to lack of water, mostly barren land or dry land, so far With the communes of the people, many questions have been asked about the issue of irrigation on newly reclaimed wasteland and the problem of drought and water change
