【摘要】：本文采用碳足迹分析方法,研究湖南省典型水稻生态系统---稻田多熟制生态种养系统的碳汇功能和生态补偿标准,有利于制定湖南省水稻生产系统的生态补偿建议,促进湖南省乃至全国水稻产业的健康发展。主要研究结果如下：(1) 稻鸭生态种养系统单位面积的双季稻周年生产系统平均固碳能力为8172.OkgC.hm-2,双季稻周年生产系统每生产lkg的干物质相当于固定0.621kgC。而稻鱼生态种养系统单位面积的双季稻周年生产系统平均固碳能力为7586.9kgC.hm-2,双季稻周年生产系统每生产lkg的干物质相当于固定0.607kgC。(2) 以单位面积为基础,稻鸭生态种养系统的早、晚季的碳汇分别为2105.83kgC/hm2和2674.29kgC/hm2,稻鱼生态种养系统早、晚季的碳汇分别为2044.72kgC/hm2和2555.1 OkgC/hm2。而以单位经济产量为基础,稻鸭生态种养系统早、晚季的碳汇分别为0.335kgC/kg和0.390kgC/kg,稻鱼生态种养系统早、稻季的碳汇分别为0.343kgC/kg和0.392kgC/kg。(3) 以单位面积为基础,得出稻鸭生态种养系统早、晚季分别需要补偿526.5元/hm2、628.7元/hm2,稻鱼生态种养系统早、晚季分别为511.2元/hm2和638.8元/hm2。而以单位经济产量为基础,稻鱼生态种养系统早、晚季分别需要补偿0.0856元/kg、0.0981元/kg,稻鸭生态种养系统早、晚季分别为0.0837元/kg、0.0975元/kg。
[Abstract]:In this paper, carbon footprint analysis method is used to study the carbon sink function and ecological compensation standard of typical rice ecosystem in Hunan Province, which is the multi-cropping ecological system of paddy field, which is helpful to formulate ecological compensation suggestions for rice production system in Hunan Province. To promote the healthy development of the rice industry in Hunan Province and even throughout the country. The main results were as follows: (1) the average carbon sequestration capacity of the annual production system of double-cropping rice was 8172.Okg C.hm-2, and the dry matter of lkg per annual production system was equal to 0.621kgC. The average carbon sequestration capacity of the two-cropping rice production system per unit area was 7586.9 kg C.hm-2, and the dry matter per lkg production system was equal to that of 0.607kgC. (2) based on the unit area, the carbon sequestration capacity of the annual production system was 7586.9kgC.hm-2.The average carbon sequestration capacity of the annual production system was 7586.9kgC.hm-2. The early and late season carbon sinks of rice-duck ecological breeding system were 2105.83kgC/hm2 and 2674.29kgC / hm ~ 2, respectively. The early and late season carbon sinks of rice-fish ecological breeding system were 2044.72kgC/hm2 and 2555.1 OkgC/hm2., respectively. On the basis of yield per unit economy, the carbon sinks of rice-duck ecological breeding system and late season were 0.335kgC/kg and 0.390 kgC / kg, respectively, and the rice-fish ecological breeding system was early. The carbon sinks of rice and duck were 0.343kgC/kg and 0.392kg / kg / kg 路(3) respectively. (3) on the basis of unit area, the ecological breeding system of rice-duck was early, and the late season needed to compensate 526.5 yuan / hm2628.7 / hm2, early. Late quarter: $511.2 / hm2 and $638.8 / hm2. On the basis of yield per unit economy, rice and fish ecological breeding system needs to compensate 0.0856 yuan / kg,0.0981 / kg, early in late season and 0.0837 yuan / kg,0.0975 / kg. in late season, respectively.
