摘要:

分析了太湖流域城市人均生活垃圾年清运量的变化趋势及影响因子:家庭规模、年龄分布年变化特征和消费性支出情况。江苏地区人均垃圾年清运量由2002年的0051 t增加到2007年的0118 t,增长1倍多(〖WTBX〗P〖WTBZ〗<005)。同时期上海和浙江增幅也分别高达60%和23%。太湖地区家庭人口数2~4人占主导地位,总和约占76%(〖WTBX〗P〖WTBZ〗<001)。2002~2007年,我国人口年龄分布逐步呈现老龄化,0~14岁人口比例逐年下降,其中上海和江苏地区的下降比例高达25%(〖WTBX〗P〖WTBZ〗<001)。统计分析结果表明:人均垃圾年清运量与家庭规模和居民消费性支出呈显著正相关关系,与年龄分布呈显著负相关关系,其中,与家庭规模的相关系数最小。最终给出了太湖流域两省一市范围内人均垃圾年清运量的相关预测方程,并利用浙江省太湖地区的数据进行验证,吻合程度较高。〖

Abstract:

Annual variations on collected amount of percapita municipal solid waste (MSW) in Taihu Lake Basin as well as the influencing factors were analyzed in this study.The selected influencing factors were the family size,age distribution of residents,and household consumption expenditure.From 2002~2007,the collected amount of percapita MSW in shanghai city increased from 3.77 million tons to 791 million tons,which was almost doubled (〖WTBX〗P〖WTBZ〗<0.05).Within the same period,the collected amount of MSW from Jiangsu and Zhejiang provinces increased by 58% and 25%,respectively.The family size with 2~4 people dominated in Taihu Lake Basin and their sum accounted for about 76% (〖WTBX〗P〖WTBZ〗<001).From 2002 to 2007,the age distribution of Chinese resident has showed the signs of aging.The proportion of people between the ages of 0~14 decreased yearly.Among those,Shanghai city and Jiangsu province decreased 25% (〖WTBX〗P〖WTBZ〗<001).Statistical analysis showed that the collected percapita MSW was significant positive correlated with the family size and the amount of household consumption expenditure.There was a significant negative correlation between amount of the collected MSW and the age distribution.Correlation coefficient between the collected MSW and the family size was the minimum.The related prediction equation was built on family size,age distribution,and household consumption expenditure for Taihu Lake Basin.The prediction equation was validated using the data from Zhejiang province,which was consistent between the original and the calculated date with a high degree.〖
