Abstract

The urban soil was an important part of urban ecosystems.In this paper,six forest types were selected for the study in Shahe River landscape ecology shelterbelts.They were Locust forest,privet-elm forest,Ficus virens-privet forest which was multiple storied tree,shrub and grass and Metasequoia forest,bamboo forest and Palmetto forest which was multiple storied tree and grass.Comparative studies were conducted on the soil mechanical composition,porosity,and total nitrogen,total phosphorus,total potassium content of major nutrients.The results showed that ① privet-elm forest had the highest content of clay and silt in six forest types,being 7.79%±0.06% and 60.01%±0.15%;and followed by Ficus virens-privet forest and locust forest second;and Palmettoand bamboo forests had the lowest content; ② Soil porosity and capillary porosity showed the highest in locust forest,being 47.41%±0.79% and 44.22%±0.87%;Several other forests showed privet-elm forest > Ficus virens-privet forest > bamboo forest > Metasequoia forest > Palmetto forest in descending order.③ Soil total nitrogen,total phosphorus and total potassium content showed the highest in privet-elm forest; Soil total nitrogen and total potassium content showed the lowest in Metasequoia forest; Soil total phosphorus showed the lowest in Palmetto forest.④ Considering the soil mechanical composition,porosity,and total nitrogen,total phosphorus,total potassium content of major nutrients,the privet-elm forest which was multiple storied tree,shrub and grass showed the best.
