使用市场价格替代法、影子工程价格法及现行市价法等评价方法,对廊坊市建成区森林涵养水源、保持土壤、净化空气、固碳制氧等服务功能进行了初步估算。以2000年为基准年,以2001—2005年、2006—2010年及2011—2015年为估算时段综合分析、预测廊坊市建成区森林生态系统生态资产的动态变化趋势。结果显示:廊坊市建成区森林生态系统生态资产2000年、2005年、2010年及2015年分别为1 448.818 6万元、2 733.072 4万元、4 098.457 6万元及4 692.988 4万元,人均生态资产占有量分别为43.573 5元/人、74.268 3元/人、90.076 0元/人及86.427元/人;2001—2005年、2006—2010年及2011—2015年3个评价时段中生态资产增长率依次为88.641 5%,49.957 9%及14.506 3%,而同期人均生态资产占有量增长率依次为70.443 7%,21.284 6%及-4.051 0%。
Using market price substitution method, shadow engineering price method and current market price method, this paper makes a preliminary estimation of service functions of forest water conservation, soil conservation, air purification and carbon sequestration and oxygenation in built-up areas of Langfang City. Taking 2000 as the base year and 2001-2005, 2006-2010 and 2011-2015 as the comprehensive analysis of the estimated period, the dynamic change trend of forest ecosystem ecological assets in the built-up areas of Langfang City was predicted. The results showed that the ecological assets of forest ecosystems in built-up areas of Langfang City were respectively 1 448.818 million yuan, 2733.072 million yuan, 4 098.457 million yuan and 4 692.988 4 million yuan in 2000, 2005, 2010 and 2015 respectively, The share of ecological assets was 43.573 yuan / person, 74.268 yuan / person, 90.076 yuan / person and 86.427 yuan / person respectively. In the three evaluation periods of 2001-2005, 2006-2010 and 2011-2015, the ecological assets The growth rates were 88.641 5%, 49.957 9% and 14.506 3% respectively, while the growth rate of the average per capita ecological asset occupancy in the same period was 70.443 7%, 21.284 6% and -4.051 0% respectively.
