| 摘 要： | 风沙灾害是冬春季节我国北方地区面临的最为严峻的生态问题.应用物元法模型对北京市大兴区进行风沙灾害危险性评价.结果表明,由于人为活动较强烈,毗邻北京中心城区的大兴区北部较南部危险等级高.扩大绿化面积、改良土壤、减少人为扰动是减少风沙危害的有效途径. |

| Abstract: | Sandstorm disaster is one of the most serious ecological problems in northern China in winter and spring.Matter-element method model was carried out on the sand hazard evaluation in Daxing District,Beijing.The results showed that,due to more intense human activities,the risk level in the north of Daxing District adjacent to downtown of Beijing was higher than the south.There are effective ways to reduce sandstorms damage,such as expanding green areas,improving the soil,and reducing human interference. |
