江苏是个人多地少,木材、薪柴奇缺的省份.如何充分合理地利用土地资源,乃是当务之急.徐淮地区是本省面积最大、人口最多的一个农业区,在全省占有重要地位.本区地处淮、沂、沭、泗四河下游,地势低平,大部分土地处于洪水威胁之下,依靠堤防保护,才能免遭淹没.本区雨量充沛,但时空分布不匀.洪、涝、旱、渍等灾害,远未根本消除,生态系统比较脆弱.这里河渠纵横,密如珠网,如何保障境内水系畅通,使之沟通流域内航行、交通和保证工农业用水的同时,又维持自然环境的生态平衡,同时众所关心的问题.为此,本人不揣浅陋,根据参加徐淮地区综合考察所得材料及平时所见所闻,就徐淮地区河 Jiangsu is a province with a small number of individuals and a shortage of wood and fuelwood.How to make full and rational use of land resources is a priority.Huaihua is an agricultural area with the largest area and the most populous province in the province and occupies an important position in the province. The area is located in Huai, Yi, Shu, Si Sihe lower reaches, the low terrain, most of the land under the threat of floods, relying on the embankment protection, in order to avoid flooding.The area has plenty of rainfall, but uneven temporal and spatial distribution.Hong, Floods, droughts and stains are far from being completely eradicated and their ecosystems are fragile, where the vertical and horizontal canals are densely covered with beads. How to ensure the smooth flow of water within the watershed so that they can communicate with the navigation, traffic and industrial and agricultural water in the basin? To maintain the ecological balance of the natural environment, while the public are concerned about the issue.To this end, I do not speculate shallow, according to participate in Xuhuai region comprehensive inspection of the materials and usually seen and heard about the Xuhuai River
