| 摘 要： | 基于2005年深圳市森林资源二类调查资料数据,采用材积源生物量法,计测深圳市森林植被碳储量和碳密度,分析了深圳市森林植被碳储量空间分布格局.结果表明,2005年深圳市森林植被总碳储量为225.04×104Mg,平均碳密度为25.63MgC·hm-2.深圳市各区的森林植被碳储量空间分布上有显著差异.表现为龙岗区(123.13×104Mg)>宝安区(46.70×104Mg)>盐田区(20.49×104Mg)>罗湖区(14.75×104Mg)>南山区(12.79×104Mg)>福田区(5.63×104Mg)>保护区(1.57×104Mg).各区碳密度分布为盐田区(46.18MgC·hm-2)>福田区(37.63 MgC·hm-2)>罗湖区(36.78MgC·hm-2)>龙岗区(26.60MgC·hm-2)>保护区>(24.19 MgC·hm-2)>宝安区(19.53MgC·hm-2),与碳储量大小分布无明显相关.深圳市乔木林碳储量为146.11×104Mg,以中幼龄林为主,占73.2%,平均碳密度为30.76MgC·hm-2.根据森林植被碳储量与碳密度的空间差异性对深圳市森林进行了区划,并分区提出了提高深圳市森林碳吸存能力的有效措施.

| Abstract: | Based on the forest resource inventory data of 2007 in Shenzhen City,the carbon storage and carbon density were measured using the volume-derived method,and spatial distribution pattern of forest carbon was also studied.The results showed that total forest carbon of 2005 in Shenzhen City was 225.04×104Mg.The average carbon density was 25.63 Mg C hm 2.Spatial distribution patterns of forest carbon in each district of Shenzhen city were significantly different,which were in the order of Longgang District(123.13×104 Mg)> Bao’an District(46.70×104Mg)> Yantian District(20.49×104Mg)> Luohu District(14.75×104Mg)> Nanshan District(12.79× 104 Mg)> Futian District(5.63×104Mg)> protected areas(1.57 × 104Mg).Carbon densities in each district of Shenzhen City were not significantly correlated to spatial distribution patterns of forest carbon,which were sequenced as Yantian District(46.18 Mg C hm 2)> Futian District(37.63 Mg C hm 2)> Luohu District(36.78 Mg C hm)> Longgang District(26.60 Mg C hm 2)> protection area>(24.19 Mg C hm 2)> Bao’an District(19.53 Mg C hm 2).Carbon storage of high forest was 146.11×104Mg,in which the young forest accounted for 73.2%.The average carbon density was 30.76 Mg C hm 2.Forest division in Shenzhen City was studied based on the spatial difference between forest carbon storage and carbon density,and the effective measures to improve the forest carbon sequestration were proposed. |
