绥芬河国家森林公园生态因子效应分析

对绥芬河国家森林公园典型样地及绥芬河市区典型对照样地的空气负离子密度、温度、湿度、二氧化碳体积分数和噪音进行了测量,并分析了森林公园与市区样地中各生态因子的日变化规律,比较了森林公园与市区、森林公园内典型样地间的空气负离子密度、温度、湿度、二氧化碳体积分数及噪音在监测时段的发生量。结果表明,森林公园与市区样地的温度、湿度日变化规律基本一致。森林公园和市区的空气负离子密度、二氧化碳体积分数和环境噪音具有各自的日变化规律。绥芬河国家森林公园空气质量和生态效益整体上高于市区。

Effect Analysis of Ecological Factors in Suifenhe Forest Park

An experiment was conducted to determine the concentrations of negative air ions,temperature,humidity,carbon dioxide concentration and noises for the typical samples in Suifenhe Forest Park and the comparable samples in Suifenhe City Area.The regularities of diurnal variations for all the ecological factors were analyzed both in the forest park and in the city area.The changing quantities of all the factors between the forest park and the city area as well as among the typical samples in the forest park during monitoring period were also compared.Results show that the regularities of diurnal variations for temperature and humidity in the forest park are consistent with those in the city area.The concentrations of negative air ions,carbon dioxide concentration and noises both in the forest park and in the city area have their own rhythms.The air quality and the ecological benefits in Suifenhe Forest Park are much better than those in Suifenhe City Area.
