摘　　要：【目的】林盘是成都平原十分重要的生态系统以及农户赖以生存的生产生活空间,但是当前林盘各种生态系统服务的定量评估还十分欠缺,本文将科学揭示林盘的固碳释氧功能和价值。【方法】本文通过小型无人机与地面植物调查,利用材积-生物量模型和平均生产力法估算乔木与竹林的固碳释氧物质量,并采用造林成本法和工业制氧法测算其价值量。【结果】林盘内维管束植物合计106科254属310种,包括乔木81种和竹类11种,不同规模林盘的物种种类和数量具有一定差异性;小、中、大型林盘平均碳储量约为6.36、21.91和43.72 t/个,固碳能力约为0.26、0.81和1.56 t/a.个,固碳释氧价值量分别为456.05、1438.32和2762.63元/a.个;【结论】总体上看,郫县林盘2015年碳储量约为75594.36 t,固碳能力约为2885.74 t/a,固碳释氧的价值量约为509.73×10~4元/a,其中固定CO2247.17×10~4元/a,释放O2262.56×10~4元/a。【Objective】As the trsditional settlement pattern formed by farm house and the surrounding trees with integration of production and living,Linpan is a very important ecological system in Chengdu plain.Currently,the ecosystem services of Linpan were not be quantitative analysis.【Method】In this study,the basic data were be obtained by small unmanned aerial vehicle(UAV)and field survey,Volume-biomass and forest productivity model were used to estimate the carbon fixation and oxygen releasing ability of Linpan in Pi county.Then,forestation cost method and industrial oxygen generation method were used to compute the values of carbon fixation and oxygen releasing.【Result】There were 310 plants species belonging to 254 genera and 106 families in the survey area,including 81 tree species and 11 bamboo species.According to the investigation,the number of plant species and quantity were obviously different between small Linpans and medium-large ones.The average of carbon reserves of small,medium and large Linpan were 6.36,21.91 and 43.72 t.Thus,the ability of storage carbong of small,medium and large Linpan were 0.26,21.91 and 43.72 t/a.The economic value of carbon fixation and oxygen release of small-medium-large size Linpan were also different.As a result,the practical valuation of carbon fixation and oxygen release provided by small Linpan were 456.05 yuan RMB per year,among medium and large Linpan were 1438.32 yuan RMB per year and 2762.63 yuan RMB per year.【Conclusion】Based on the above analysis of different scale Linpan in Chengdu plain,It was estimated that the total amount of carbon storage of Linpans in Pi county about 7.56×10 4 t and the ability of storage carbon was about 0.29×10 4 t/a.Meanwhile,the econmic values of carbon fixation and oxygen release were 262.56×10 4 yuan RMB in 2015,and the values of carbon fixation were 247.17×10 4 yuan RMB,while those of oxygen releasing were 262.56×10 4 yuan RMB.
