| 摘 要： | 稻田生态系统对整个农业生态系统的组成具有极大的实际意义,为各类生物提供生长条件的同时,也为人类的生存与发展提供了重要的产品与服务.以湖南省稻田为研究区,采用造林成本法、工业制氧法以及当量因子法的等方法对稻田生态系统八项功能进行测算。结果表明,2016年湖南省稻田生态系统服务价值为2.47万元/hm^2,其中为稻田生态系统正面服务4.36万元/hm^2,其负面生态价值为1.83万元/hm^2,正面生态价值是其负面生态价值的2.4倍。因此评价稻田生态系统的生态服务价值对整个农业生态系统及区域环境研究具有重要的意义。

| Abstract: | The Eco-system of the paddy field has a very significant meaning for the constitution of the whole agricultural Eco-system.The Eco-system of the paddy field can provide growth condition for different kinds of living things,at the same time,it provides important products and services for the survival and development of human beings.In this paper,our research is based on the rice field of Hunan Province.And the method of forestation cost,industrial oxygen production process,and equivalent factor method,as well as other different methods are adopted in this paper to calculate the eight functions of the paddy field Eco-system.The result shows that,in 2016,the service value of paddy field Eco-system in Hunan Province is 24700 Yuan/hm2,among which the the positive service of the paddy field's eco-system is 43600 yuan/hm2,and its negative ecological value is 18300 yuan/hm2.The positive ecological value is almost twice as much as the negative value.Therefore,evaluating the ecological value of the paddy field's eco-system has a very significant meaning for the whole agricultural eco-system and the research of regional environment. |
