【摘要】：實(shí)施土地整理工程,不僅能夠提供產(chǎn)能,而且能夠減少農(nóng)田碳排放。以河北省巨鹿縣王虎寨鎮(zhèn)土地整理項(xiàng)目為例,通過(guò)GIS空間分析方法,最優(yōu)可達(dá)性分析等研究方法,研究了土地整理項(xiàng)目前后廊道結(jié)構(gòu)變化及生產(chǎn)方式的改變導(dǎo)致的碳源碳匯、碳排放特征及其規(guī)律的相對(duì)差異,并對(duì)農(nóng)田防護(hù)林固碳量和田間運(yùn)輸?shù)目s減碳排放量進(jìn)行了計(jì)算。結(jié)果表明:農(nóng)田防護(hù)林10 a累計(jì)固碳量可達(dá)2.63×10~6kg,年固碳量在9×10~4~4.5×10~5kg/a之間,固碳高峰期在防護(hù)林種植后3~6 a,而后逐漸降低趨于穩(wěn)定;田間道路的新建與整修后,在單田塊機(jī)械作業(yè)方式下,田間運(yùn)輸年節(jié)約柴油2.16×10~4kg/a,碳減排量達(dá)1.28×10~4kg/a;規(guī)模化作業(yè)方式比單戶自營(yíng)最大可減少86.7%碳排放量�？傮w來(lái)看,巨鹿縣土地整理工程在農(nóng)田防護(hù)林及田間運(yùn)輸角度對(duì)農(nóng)田碳排放降低有一定效果。
[Abstract]:The implementation of land consolidation projects can not only provide production capacity, but also reduce carbon emissions from farmland. Taking the land consolidation project in Wanghuzhai Town, Julu County, Hebei Province as an example, through the GIS spatial analysis method, the optimal accessibility analysis and other research methods are used. In this paper, the relative differences of carbon sink, carbon emission characteristics and their laws caused by structural change of corridor and change of production mode before and after land consolidation project were studied. The carbon sequestration of farmland shelterbelt and the reduction of carbon emission from field transportation were calculated. The results showed that the accumulative carbon sequestration of farmland shelterbelt in 10 years could reach 2.63 脳 10 ~ (-6) kg, and the annual carbon sequestration was between 9 脳 10 ~ (10) ~ 44.5 脳 10 ~ (5) kg / a. The peak period of carbon sequestration was 3 ~ 6 years after planting in the shelterbelt, and then gradually decreased to a stable level. After the construction and renovation of the field roads, under the single-field mechanical operation mode, Field transportation saves 2.16 脳 10 ~ (10) ~ 4 kg / a of diesel oil and reduces carbon emissions by 1.28 脳 10 ~ (10) ~ 4 kg / a per year. Land consolidation project in Julu County has certain effect on carbon emission reduction in farmland shelterbelt and field transportation.
