龙感湖湿地主要种植模式生态经济效益分析

Ecological and economic benefits of the main planting patterns in Longgan Lake wetland

实地调查了龙感湖湿地的水稻-小麦、水稻-油菜、茭白-冬闲、莲藕-冬闲和芋头-冬闲五种种植模式并进行生态经济效益的综合分析。分析结果表明,茭白-冬闲的纯收入最高,莲藕-冬闲次之;二者的成本收益和劳动生产率高于其他模式;二者的生态经济效益较为理想。

Five planting patterns have been investigated, which are rice-wheat, rice-rape, cane shoot-idle field; lotus root-idle field; and taro-idle field, on their ecological and economic benefits. The net income of the last pattern ranks first, followed by the pattern of lotus root-idle field. The two patterns are most favorable.
