| 摘 要： | 通过对长江中游四湖地区地下水动态观测数据分析得出，长江对沿岸平原地下水影响程度随距离增大而逐渐减弱。用遥感技术和实地调查，确定了潜育化、沼泽化土壤在四湖和沿庭湖地区分布以及潜在威胁面积。并依此分析了三峡工程对土壤潜育化沼泽化的影响。在大量调查和田间试验的基础上，提出了适用于当地的潜育化沼泽化土壤改良利用途径。

| 关 键 词： | 三峡工程，长江中游，地下水动态，土壤潜育化沼泽化，改良利用 |

| Abstract: | The ground water dynamics in the Four lake region of middle reaches of the Yangtze River was observed.The result showed that effect of the Yangtze on ground water in plain area decreased with the distance from the river.Furthermore,the distribution and potential influenced area of the gleying and swamping soil in the Four lake and Dong ting Lake region were determined by means of remote sensing and field investigation.The effect of the Three Gorge project on soil gleyization and swamping was discussed according to the above results.The proper ways of amelioration and utilization of gleying and swamping soils were presented on the basis of a large number of field investigations and experiments. |
