| 本文通过野外考察和采样分析,就旅游和城市化对避暑山庄土壤、植物的影响方式、程度以及采取的生态学措施进行了初步探讨,结果表明,山庄土壤紧实度增加、孔隙度减少,碱度提高,硫含量是北京植物园土壤的2.1倍;植物遭受到人为引起的病虫害、机械破坏以及环境污染的影响,突出地表现在古松死亡严重(26.5棵/年)。 |
| 英文摘要 |
| In order to study the impact of both tourism and urbanization, the authors have investigated soil and plants at the Summer Villa, a former imperial garden in Chen-de City of Hebei Province. The results show that soil density and alkalinity have increased, and soil areation decreased. Sulphur concentration in soil is 2.1 times higher as in Beijing Botanical Garden, and plants have been injured by pests and pollution, for example, losts of old pine trees died in past few years. In addition, the authors proposed some ecological strategies to handle the problems. |
