里下河位于扬州市北部,湖荡众多,沟河交错。本地区气候不稳定,自然灾害比较频繁,尤以水灾、风灾较为严重。建国以来,由于大兴水利建设,初步建成了沟、渠、路、圩配套的水利网络系统,使农业生产条件得到改善,但自然灾害仍未彻底消除,农田林网建设仍为必要。 为了确保农业稳产高产,建立良性循环的生态系统,同时解决本区用材难的问题,我们于1981年在江都县锦西乡延寿村和兴化县海南乡南蒋村设点进行了池杉农田林网研究,现将取得的初步结果报告如下:
Lixiahe is located in the northern part of Yangzhou City, with numerous lakes and dikes crossing the river. The climate in this region is unstable and natural disasters are frequent, especially in floods and typhoons. Since the founding of the People’s Republic of China, due to the construction of Daxing water conservancy, a network system of irrigation and drainage network with ditches, drains, roads and polders has been initially built to improve agricultural production conditions. However, natural disasters have not yet been completely eliminated and farmland network construction is still necessary. In order to ensure a stable and high-yield agriculture, establish a virtuous cycle of ecosystems, and solve the problem of using materials in this area, we conducted a taxonomic study of taxus in Yanzong Village, Jinxi Township, Jiangdu County, and the South Jiang Village, Hainan Township, Xinghua County in 1981 Lin network research, the initial results will now be reported as follows:
