摘要
选择我国小城镇发展较为迅速的浙中地区（主要以巍山镇为例），采用变量相关的生态学方法，对其城镇化过程的生态风险评价作了尝试。结果表明，癌症和高血压等“文明病”的发病率随着城镇化水平的提高而逐年上升，具体表现为与城镇居住人口（包括农业人口和非农业人口）密度、居民人口增加、年龄、性别、乡镇工业和交通发展等有关，是城镇生态系统中有害物浓度和输入通量增加对人类生存与发展作用的结果，反映了城镇化过程中所遭受的生态代价与风险。
Ecological risks of urbanization processes of some towns(taking Weishan Town as an example,located in the middle part of Zhejiang Province,a rapid developing area of towns)were assessed using the ecological method of the variable interrelation.The results indicate that the incidence of “civilization diseases” such as cancer and hypertension has been year after year increasing with a rise in urbanization levels.The trend was related to the density of population (including agricultural population and nonagricultural population) in a town,the increment of proportion of residents,the age and sex of residents,and the development of rural industry and communications.It was also related to the action of the increment in concentrations and fluxes of harmful substances in urban ecosystems on human existence and development.It concretely reflects the ecological costs and risks which are suffered in the process of urbanization.
