摘　　要：在稻田生态系统服务功能研究中,稻田养蟹生态系统服务功能总价值为50927.97元/hm^(2),其中生产功能价值为22146.18元/hm^(2),生态功能价值为28781.79元/hm^(2);对照区生态系统服务功能总价值为41730.96元/hm^(2),其中生产功能价值为13832元/hm^(2),生态功能价值为27898.96元/hm^(2)。养蟹区生态系统服务功能比不养蟹区生态系统的服务功能价值高出882.83元/hm^(2)。稻田养蟹具有良好的经济收益、生态效益,是一种顺应可持续发展的稻田生态种养模式。充分认识稻田生态种养模式的综合功能对实现有效的利用稻田资源,保护生态环境有着重要意义。In the study of the ecosystem service function in rice field,the total value of paddy crab ecosystem service function is 50927.97 yuan/hm^(2),which the production function value is 22146.18 yuan/hm^(2) and the ecological function value is 28781.79 yuan/hm^(2).The total value of ecosystem service function in the control area was 41730.96 yuan/hm^(2),of which the production function value was 13832 yuan/hm^(2) and the ecological function value was 27898.96yuan/hm^(2).The value of ecosystem service function in crab farming area is 882.83 yuan/hm^(2) higher than that in non-crab farming area.Rice-crab model has good economic benefits and ecological benefits,and it is a kind of ecological planting and breeding mode of rice paddy that conforms to sustainable development.It is great significance to realize the effective utilization of rice field resources and protect the ecological environment to fully understand the comprehensive function of ecological planting and breeding model of rice field.
