黑龙江省森林资源生态产品产能

Eco-product production capacity of forest resources of Heilongjiang Province

基于黑龙江省森林资源二类调查数据和森林生态站长期监测数据,利用森林生态功能修正系数对森林资源生态产品产能(森林生态系统服务功能)进行评估,探讨各市/地区间的森林生态系统服务功能分布格局,以及不同林分结构对评估结果的影响。结果表明,大兴安岭地区、黑河市和牡丹江市的森林生态系统服务功能位于其他市/地区前列,全省森林生态系统涵养水源量相当于本省地表水量的72.88%,以及2004—2008年间全国、辽宁省和吉林省年森林涵养水源量的10.25%、6倍和4倍;固碳量相当于抵消了本省工业碳排放量的67.61%,而2004—2008年间全国、辽宁省和吉林省年森林固碳量相当于抵消本区域内年工业碳排放量的9.97%、4.94%和14.70%。

Based on forest resource inventory data and long-term observation data from forest eco- logical stations in Heilongjiang Province, eco-product production capacity of forest （forest ecosys- tem services） at city/region scale in Heilongjiang Province was assessed with forest ecological function correction coefficient. Accordingly, the spatial distribution pattern of forest ecosystem services and the influence of different stand structures on forest ecosystem services were dis- cussed. The results showed that the top three cities/regions in terms of forest ecosystem services were Daxinganling region, Heihe City, Mudanjiang City in Heilongjiang Province. The water con- servation amount of forest ecosystems was equivalent to 72.88% of the surface water amount in Heilongjiang Province, and 10.25% of water conservation amount of forest ecosystems in China, 6 times of that in Liaoning Province, and 4 times of that in Jilin Province during 2004 to 2008. The amount of carbon fixed by forest ecosystems in Heilongjiang Province was equivalent to 67.61% of the industrial carbon emission amount in Heilongjiaug Province. Over the same peri- od, this ratio was 9.97%, 4.94% and 14.70% for whole China, Liaoning Province and Jilin Province, respectively.
