驻马店国家森林城市建设生态服务价值分析

Analysis on the ecological service value of Zhumadian national forest city construction

为了研究森林城市建设生态服务价值的变化规律,采用驻马店市森林资源清查数据、林业统计数据、森林生态服务功能观测数据,对驻马店市森林城市建设的生态服务价值进行了评估。结果表明:驻马店市建设国家森林城市7年来,森林面积增加了129 729 hm^(2),其中山区森林面积增加了43 856 hm^(2),平原林面积增加了81 448 hm^(2),城市绿地增加了1 645 hm^(2),经济林地面积增加了2 780 hm^(2)。2022年国家森林城市建设生态服务价值比2016年增加了1 215 995万元(人民币,下同),其中山区森林生态服务价值增加了405 251万元,平原林生态服务价值增加了769 310万元,城市绿地生态服务价值增加了15 300万元,经济林木生态服务价值增加了26 129万元。在国家森林城市建设增加的森林生态服务价值中,涵养水源价值增加了24.96%,保育土壤价值增加了29.64%,固碳释氧价值增加了32.45%,林木养分固持价值增加了2.75%,净化大气环境价值增加了3.64%,生物多样性保护价值增加了7.56%。国家森林城市建设扩大了森林面积,改善了区域环境质量,生态效益显著。

In order to study the change law of ecological service value of forest city construction,theecological service value of the construction of the national forest city in Zhumadian were evaluated using theinventory data of forest resources,forestry statistics and forest ecological service function observation data. Theresults showed that the forest area increased 129 729 hm^(2), including 43 856 hm^(2) in mountainous areas,81 448 hm^(2) in plain forests,1 645 hm^(2) in urban green spaces,and 2 780 hm^(2) in economic forest areas. Theecological service value of national forest city construction increased by 12 159. 95 million yuan from 2016 to2022,including 4 052. 51 million yuan of mountainous forest ecological service value,7 693. 10 million yuan ofplain forest ecological service value,153. 00 million yuan of urban green space ecological service value,and261. 29 million yuan of economic forest ecological service value. Among the added value of forest ecologicalservices in the construction of national forest cities,the value of water conservation increased by 24. 96%,thevalue of soil conservation increased by 29. 64%,the value of carbon fixation and oxygen release increased by32. 45%,the value of forest nutrient fixation increased by 2. 75%, the value of purifying the atmosphericenvironment increased by 3. 64%,and the value of biodiversity protection increased by 7. 56%. The constructionof national forest cities expanded the forest area,improved the regional environmental quality,and achievedsignificant ecological benefits.
