| 摘 要： | 运用直接市场评价法和间接市场评价法对免耕抛秧稻-鸭生态种养模式、免耕抛秧不养鸭种植模式、翻耕抛秧不养鸭种植模式生态系统物质生产功能、调节大气功能、节水功能、涵养水源功能、营养物质保持功能等价值进行了货币化定量评价.结果表明:免耕抛秧稻-鸭生态种养模式生态系统服务价值为22 080.28元/hm2,比免耕抛秧不养鸭高54.83%,比翻耕抛秧不养鸭高73.92%.免耕抛秧稻-鸭生态种养模式物质生产功能价值为10 198.70元/hm2,调节大气功能价值为9 521.92元/hm2,节水功能价值为871元/hm2,营养物质保持功能价值为847.33元/hm2,涵养水源功能价值为641.33元/hm2.

| Abstract: | By way of direct and indirect marketing evaluation,contrastive study of monetized quantitative evaluation has been made on duck-ecosystem with no-tillage seedling-throwing rice,no-tillage cropping patterns with no duck-breeding,tillage cropping patterns with no duck-breeding three kinds of rice patterns of ecosystem function of material production,adjustment function of atmosphere,water-saving function,water conservation function,nutrient-retaining function and so on. The results show that the value of duck... |
