【摘要】：森林碳匯是森林生態(tài)效益的組成部分,是衡量森林城市創(chuàng)建的重要指標之一。本文以株洲市森林城市的創(chuàng)建為背景,以株洲市的杉木林、馬尾松林、國外松林、速生闊葉林、中生闊葉林和慢生闊葉林等主要的森林類型為研究對象,結(jié)合國家森林城市評價指標體系,采用2014年株洲市森林“二類調(diào)查”及室內(nèi)實驗數(shù)據(jù),利用蓄積量法和碳稅法對株洲市森林碳匯效益和主成分分析法對影響株洲市森林碳匯效益的因素進行了分析。以挑選出固碳能力強、碳匯效益好的骨干樹種及森林群落類型,為株洲市的國家森林城市建設和林業(yè)資源的合理利用提供了數(shù)據(jù)支持和理論基礎(chǔ)。具體結(jié)果如下：(1)株洲市不同森林類型單位面積生物量因林種的不同而存在一定的差異。具體表現(xiàn)為：慢生闊葉林(128.25 t.hm-2)中生闊葉林(115.63 t.hm-2)速生闊葉林(93.05 t.hm-2)杉木林(41.98 t.hm-2)國外松林(20.57 t.hm-2)馬尾松林(19.76 t.hm-2)。(2)株洲市森林碳匯功能及效益明顯。森林總固碳量為137.95萬t,森林土壤固碳量114.84萬t,林木固碳量23.11萬t。針葉林固碳量是闊葉林的2.93倍,針葉林為固碳能力強、固碳效益最好的森林群落。株洲市森林碳匯效益的價值量為8.92億元,相當于株洲市2013年的GDP(1960億元)的0.46%。(3)株洲市森林林木碳匯功能隨森林特征而呈現(xiàn)出一定規(guī)律性。從不同的森林類型來看,杉木林林木碳匯量最高為117367.40t,其次為慢生闊葉林67856.28t,馬尾松林最少僅為2540.67t；從不同林齡階段來看,中齡林最高為159815.55t,其次為幼齡林,63701.93t,成熟林最少為1023.27t。(4)株洲市不同森林類型土壤碳匯量隨土層、森林類型呈現(xiàn)出明顯的規(guī)律。株洲市不同森林類型土壤A層有機質(zhì)(有機碳)含量高于B層。不同的森林類型土壤碳匯量表現(xiàn)為：杉木林慢生闊葉林速生闊葉林國外松馬尾松中生闊葉林。其中杉木林土壤碳匯量最高,為78.18萬t,占株洲市土壤碳匯量的68.08%；馬尾松林最低為3.23萬t,占2.81%。(5)國家森林城市創(chuàng)建后株洲市不同森林類型林木碳匯效益增加。株洲市2009年森林林木碳匯量為199293.71t,2014年森林林木碳匯量為2331137.43t。2009年森林林木碳匯量明顯低于株洲市森林城市創(chuàng)建以后的森林林木碳匯量。表明國家森林城市的創(chuàng)建增加了株洲市森林碳匯效益,城市森林生態(tài)系統(tǒng)得到了優(yōu)化。(6)影響株洲市森林碳匯效益發(fā)展的有三個主要因素：社會經(jīng)濟因素、政策法規(guī)因素、自然環(huán)境因素。其中影響最大的為社會經(jīng)濟和政策法規(guī)因素。
[Abstract]:Forest carbon sink is an integral part of forest ecological benefit and one of the important indexes to measure the establishment of forest city.In this paper, the main forest types of Chinese fir forest, Masson pine forest, foreign pine forest, fast-growing broad-leaved forest, mesophytic broad-leaved forest and slow broad-leaved forest are taken as the background of the establishment of the forest city in Zhuzhou.Combined with the evaluation index system of national forest cities, the "second class forest survey" and indoor experimental data of Zhuzhou City in 2014 were used.The effects of forest carbon sequestration and principal component analysis (PCA) on forest carbon sequestration benefit in Zhuzhou city were analyzed by means of volume method and carbon tax law.In order to select the backbone tree species and forest community types with strong carbon sequestration ability and good carbon sink benefit, this paper provides data support and theoretical basis for the national forest city construction and the rational utilization of forestry resources in Zhuzhou City.The specific results are as follows: (1) the biomass per unit area of different forest types in Zhuzhou city is different with different forest species.The results were as follows: slow broad-leaved forest (128.25 t.hm-2)) medium broadleaved forest (115.63 t.hm-2) fast broadleaved forest (93.05 t.hm-2)) Chinese fir forest (41.98 t.hm-2) (foreign pine forest 20.57 t.hm-2) Pinus massoniana forest 19.76 t.hm-2m-2) forest carbon sink function and benefit in Zhuzhou city.The total carbon sequestration of forest is 1.3795 million t, the carbon sequestration of forest soil is 1.1484 million t, and the carbon sequestration of forest is 231100 t.The carbon sequestration of coniferous forest was 2.93 times that of broad-leaved forest. The forest community with strong carbon sequestration ability and best carbon sequestration benefit was coniferous forest.The value of forest carbon sink benefit in Zhuzhou city is 892 million yuan, which is equivalent to 0.46% of 196 billion yuan in 2013 in Zhuzhou city. The carbon sink function of forest forest in Zhuzhou city shows certain regularity with forest characteristics.According to different forest types, the maximum carbon sink of Chinese fir forest was 117367.40 t, followed by slow broad-leaved forest (67856.28 t) and Pinus massoniana forest (2540.67 t).The highest value of middle age forest was 159815.55 t, followed by young forest (63701.93 t) and mature forest (1023.27 t. 4) the soil carbon sink of different forest types in Zhuzhou city showed obvious regularity with soil layer.The content of organic matter (organic carbon) in layer A of different forest types in Zhuzhou City was higher than that in layer B.The soil carbon sequestration of different forest types was as follows: Chinese fir forest, slow broadleaf forest, fast growing broadleaf forest, foreign Pinus massoniana mesophytic broad-leaved forest.The soil carbon sequestration of Chinese fir forest was the highest (781800 t), accounting for 68.08% of the soil carbon sink in Zhuzhou city, while the lowest value of Masson pine forest was 32300 t (2.81%. 5) after the establishment of the national forest city, the carbon sink benefit of different forest types increased in Zhuzhou city.The carbon sink of forest trees in Zhuzhou City in 2009 was 199293.71 t, and the carbon sink amount of forest trees in 2014 was obviously lower than that of forest trees in Zhuzhou City after the establishment of the forest city of Zhuzhou City in 2014, and the amount of carbon sink of forest trees in 2014 was obviously lower than that of forest trees in Zhuzhou City.The results show that the establishment of national forest city increases the benefit of forest carbon sink in Zhuzhou city, and the urban forest ecosystem is optimized. There are three main factors influencing the benefit development of forest carbon sink in Zhuzhou city: social and economic factors, policies and regulations.Natural environment factorsAmong them, the most influential factors are social economy and policies and regulations.
