【摘要】:本文采用碳足跡分析方法,研究湖南省典型水稻生態(tài)系統(tǒng)---稻田多熟制生態(tài)種養(yǎng)系統(tǒng)的碳匯功能和生態(tài)補(bǔ)償標(biāo)準(zhǔn),有利于制定湖南省水稻生產(chǎn)系統(tǒng)的生態(tài)補(bǔ)償建議,促進(jìn)湖南省乃至全國水稻產(chǎn)業(yè)的健康發(fā)展。主要研究結(jié)果如下:(1) 稻鴨生態(tài)種養(yǎng)系統(tǒng)單位面積的雙季稻周年生產(chǎn)系統(tǒng)平均固碳能力為8172.OkgC.hm-2,雙季稻周年生產(chǎn)系統(tǒng)每生產(chǎn)lkg的干物質(zhì)相當(dāng)于固定0.621kgC。而稻魚生態(tài)種養(yǎng)系統(tǒng)單位面積的雙季稻周年生產(chǎn)系統(tǒng)平均固碳能力為7586.9kgC.hm-2,雙季稻周年生產(chǎn)系統(tǒng)每生產(chǎn)lkg的干物質(zhì)相當(dāng)于固定0.607kgC。(2) 以單位面積為基礎(chǔ),稻鴨生態(tài)種養(yǎng)系統(tǒng)的早、晚季的碳匯分別為2105.83kgC/hm2和2674.29kgC/hm2,稻魚生態(tài)種養(yǎng)系統(tǒng)早、晚季的碳匯分別為2044.72kgC/hm2和2555.1 OkgC/hm2。而以單位經(jīng)濟(jì)產(chǎn)量為基礎(chǔ),稻鴨生態(tài)種養(yǎng)系統(tǒng)早、晚季的碳匯分別為0.335kgC/kg和0.390kgC/kg,稻魚生態(tài)種養(yǎng)系統(tǒng)早、稻季的碳匯分別為0.343kgC/kg和0.392kgC/kg。(3) 以單位面積為基礎(chǔ),得出稻鴨生態(tài)種養(yǎng)系統(tǒng)早、晚季分別需要補(bǔ)償526.5元/hm2、628.7元/hm2,稻魚生態(tài)種養(yǎng)系統(tǒng)早、晚季分別為511.2元/hm2和638.8元/hm2。而以單位經(jīng)濟(jì)產(chǎn)量為基礎(chǔ),稻魚生態(tài)種養(yǎng)系統(tǒng)早、晚季分別需要補(bǔ)償0.0856元/kg、0.0981元/kg,稻鴨生態(tài)種養(yǎng)系統(tǒng)早、晚季分別為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.
