摘要
2015年底,笔者对包头市阿尔丁植物园园林绿化情况进行了调查,并运用样本测定和回归分析等统计学方法,建立了包头市常见树种的一元及二元回归模型,对其生态功能进行定量评价。结果表明,阿尔丁植物园东园的植物绿量为1 795 479.74 m^2,吸收CO_2约为5 541 994.31 kg,释放O_2约为4 029 000.97 t,吸热约为1.05×1011k Cal,滞尘量约为242 355.29 t;其总生态经济效益折合人民币约6 508.80万元,据估算园区当年生产维护费约250万元,园区绿化植物产生的生态经济效益逐年递增。
The landscaping of Aerding Botanical Garden in Baotou city was investigated by the end of 2015. Univariate re- gression model and binary regression model of common tree species were established by using statistical methods such as sample measurement and regression analysis, and its ecological function was evaluated quantitatively. Results showed that green quantity of east garden of Aerding Botanical Garden was 1 795 479.74 m^2, the absorption of CO2 was 5 541 994.31 kg, the release of O2 was about 4 029 000.97 t, the endotherm was about 1.05 × 10^11 kCal, and dust retention was about 242 355.29 t. The total ecological and economic benefits was about 650.80 million yuan and the maintenance costs of this garden was about 2.5 million yuan. The ecological and economic benefits of green plants in the park would be increasing year by year.
