摘要
[目的]采用碳氧平衡法,对石家庄生态用地需求进行研究。[方法]应用碳氧平衡法研究了2004～2007年石家庄市碳氧的释放、吸收和平衡状况,计算了石家庄达到碳氧平衡所需的生态用地面积,并预测了2015年石家庄市碳氧平衡条件下生态用地的需求量,最后提出了改善石家庄碳氧收支状况的措施。[结果]2004～2007年,随着石家庄市经济的快速发展,其碳氧收支不平衡加剧,生态用地需求量逐年增加;若释碳耗氧量持续增长下去,到2015年所需生态用地将增至356.6万hm2,为2007年现有标准生态用地面积(157.56万hm2)的2.3倍。建议通过适当增加混交林等平均净生产量较高的植被覆盖面积,尽量开发核能、风能等绿色能源,控制人口数量等措施,改善石家庄市碳氧收支状况。[结论]该研究为石家庄市土地利用规划提供了理论依据。
[Objective] The study aimed to analyze ecological land demand of Shijiazhuang City on the basis of carbon-oxygen balance method.[Method] Firstly,the release and absorption of CO2 and oxygen in Shijiazhuang City during 2004-2007 were studied by using carbon-oxygen balance method,and the ecological land area needing for carbon and oxygen balance was calculated,then the ecological land area needing for carbon and oxygen balance in 2015 was predicted.Finally,some measures to reduce the deficit of CO2 and oxygen in Shijiazhuang were proposed.[Result] From 2004 to 2007,the unbalance between the release and absorption of CO2 and oxygen aggravated with the rapid development of Shijiazhuang City＇s economy,and the ecological land demanded increased year by year.If the release of carbon and oxygen consumption grows constantly,the needed ecological land will be nearly doubled in 2015,namely increasing to 356.6 million hm2.To reduce the deficit of CO2 and oxygen in Shijiazhuang City,they could appropriately improve the area of mixed forest and other vegetation with higher net production,develop some green energy resources like nuclear energy and wind energy,control its population and so forth.[Conclusion] The research could provide theoretical references for the overall plan of land utilization in Shijiazhuang City.
