| 中文摘要 |
| 应用"风险频数"及相关指标对沈阳地区过去30年环境风险的时空格局进行了分析。结果表明:风险频数在1966—1977及1978—1991两个时段之间的分布存在极显着差异(t=-7.353,t0.01=2.807);过去30年环境风险空间分布格局没有显着变化,但各亚区之间风险频数存在显着差异;沈阳地区存在一批高风险企业,化工行业是风险最高行业。 |
| 英文摘要 |
| The index of "risk frequency" and other relative indices are used to analyze the temporal and spateal patterns of environmental risk events in the past 30 yes in Shenyang city. The results show that there existed an extremely significant variation in the risk frequency during the periods of 1966—1977 and 1978—1979 (t=-7.353,t0.01=2.807). During the past 30 years,there was no significant variation in the spatial patterns of the evironmental risk,while the distribution of environmental risk among the districts was extremely different. In Shenyang city,there existed a series of high-risk enterprises,and the chemical industry was of the highest risk. |
