旅游和城市化对避暑山庄土壤、植物的影响

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.
