不同种养模式稻田生态系统的服务功能及价值评估
Evaluating service functions and value of ecosystemin rice fields under different models of integrated farming
摘要
Abstract
Field experiments with five kinds of ecosystems including rice monoculture model(CK),rice-crayfish coculture model(RC),rice-duck-crayfish unit release model(CRXD),rice-duck-crayfish"nomadic duck"model(NRXD),and rice-duck-crayfish large field block model(BRXD)in rice fields were conducted to evaluate the service functions and value of ecosystemin rice fields under different models of farming.The results showed that the total service value of ecosystemin rice fields under the model of CK,RC,NRXD,CRXD,and BRXD was 104 300,136 000,137 600,140 600,and 139 700 yuan/hm2,respective-ly.The average service value of ecosystemin rice fields under the models of integrated farming increased by 32.8%compared with CK.The ecological value in the 5 kinds of ecosystems accounted for 70.3%-81.0%of the total value,with the highest value in the function of regulating climate.The value of carbon sequestra-tion and oxygen release under the model of RC,NRXD,CRXD,and BRXD was 6 527.48,6 609.40,6 593.01,and 6 519.91 yuan/hm2,respectively.The service value of ecosystemin rice fields under CRXD was the highest,at 140 600 yuan/hm2 based on comprehensively analyzing the service functions of 13 ecosys-tems in rice fields and the service value of ecosystem under 4 modes of integrated farming in rice fields.It will provide reference and basis for evaluating the value of ecological service and optimizing the mode of in-tegrated farming in rice fields.关键词
