摘　　要：选取了12个省份所在的72个典型村镇进行垃圾样品采集,系统分析了我国典型村镇春季生活垃圾组成及理化特性在不同方面对村镇春季生活垃圾组成与特性进行了对比,对村镇舂季生活垃圾组成成分与理化特性进行了相关性分析,結果表明,春季村镇生活垃圾组成中以厨余类(31.39%)和灰土类(22.05%)为主,其次为橡塑类(13.84%)和纸类(14.58%),有害类(0.39%)含量最低。在舂季,村镇生活垃圾容重变化范围在82.50·398.86 kg·m^(-3)之间,平均值为256.25 kg·m^(-3);含水率在41.03%·77.53%之间,平均值为54.03%;湿基低位热值在1 056~7 553 kJ·kg^(-1)之间,平均值为3 611 kJ·kg^(-1)。村和镇的春季生活垃圾组成与理化特性无明显差异;南方地区村镇春季生活垃圾含水率高于北方地区,湿基低位热值低于北方地区;不同经济区域之间村镇春季生活垃圾组成随经济发展水平存在一定规律。村镇舂季生活垃圾湿基低位热值与厨余类、含水率存在显著负相关性,与橡塑类、纸类有显著正相关性。Domestic garbage samples from 72 villages in 12 provinces were collected and their composition and physicochemical properties were analyzed.Furthermore,the differences in the compositions and characteristics of the varying garbage samples were compared.Then,a.correlation analysis was carried out between the composition and physicochemical properties of the garbage in spring.The results showed that the domestic garbage in villages was mainly composed of kitchen waste（31.39%）,dust（22.05%）,rubber and plastics（13.84%）,paper（14.58%） and hazardous waste（0.39%） during spring.The density of rural domestic garbage varied from82.50 kg·m to 398.86 kg·m,with an average value of 256.25 kg·m.The moisture content of the domestic garbage was from 41.03%to 77.53%,with an average of 54.03%.The wet base low calorific value of the garbage was from 1 056 to 7 553 kJ·kg^-1,with an average value of 3 611 kJ·kg^-1.There was no significant difference between the garbage in the village and in town,in terms of composition and physicochemical properties,in spring.The moisture content of garbage samples was higher in the southern region than in the northern region.However,the wet base low calorific value was lower in the southern region than in the northern region.Moreover,the composition of domestic garbage was correlated to the level of economic development in spring.Wet base low calorific value of rural domestic garbage was negatively correlated to kitchen waste and moisture,while it had a significantly positive correlation with plastic and paper.
