江汉平原涝渍微地貌变异特征及生态农业模式应用研究

Variation features of micro-waterlogged topographic and ecological agriculture models in Jianghan Plain

阐述了江汉平原涝渍灾害的成因及其微地貌变异主要特征 ,根据涝渍地域微地貌差异和涝渍灾害发生特点 ,将江汉平原涝渍微地域分为 6种类型 ,并对其中广泛分布的典型碟形洼地不同高程按水体圈、涝地圈、渍地圈、旱地圈和庭院圈配置实施高效生态农业模式建设。

This paper analyzes the reason of forming waterlogged disaster and 6 variation features of micro-waterlogged region in Jianhan Plain. The land type of micro-waterlogged region in Jianghan Plain is classified to 6 kinds according to the differences of the micro-landforms and waterlogged disaster situation. A lot of ecological agricultural models are put out respectively in the lowland similar to plate shape, according to the different altitudes, named respectively water circle, flooded circle, waterlogged circle, dry field circle and courtyard circle.
