广东省森林资源及碳储量分布

利用2009年广东省森林资源监测数据，研究广东省森林资源和碳储量分布。结果表明，2009年广东省森林资源中2／3是商品林，并以一般用材林为主，速生林（含短轮伐期）的比例不到1／5，生态公益林的面积占林业用地面积1／3；各区域的森林资源中均以商品林为主，占64.7％～73.7％。商品林中除其他区域外均以一般用材林为主，占商品林面积的59.8％～81.3％，而其他区域以速生林为主。广东省的森林碳密度为32.2t／hm^2，其大小呈现粤北〉其他〉粤西〉珠三角〉粤东，森林碳储量为302.3TgC。

Distribution of forest resources and carbon stocks in Guangdong Province

Distribution of forest resources and their carbon stocks were studied using the forest resource monitoring data of 2009 in Guangdong Province. Results showed that two thirds of forests was commercial forests, mainly being composed of common timber forests, whereas fast-growing forests （including short rotation period） were less than one fifth and ecological forests accounted for onethird in Guangdong Province in 2009. Forest growing all regions was mainly consisted of commercial forests accounting for their 64.7% to 73.7%. The commercial forests were mainly consisted of common timber forests accounting for their 59. 8% to 81.3% except for the other regions, whereas fast - growing forests were in a dominant position in the other regions. Carbon density was 32.2 t/hm^2 in Guangdong Province with the order of Northern Guangdong 〉 the other regions 〉 Western Guangdong 〉 Pearl River Delta region 〉 Eastern Guangdong and carbon stock of forestry land was 302. 3 TzC （ 1 Tz = 1 012g） .
