摘要: 本文通过对成都市沙河景观生态防护林带中6种典型林分土壤理化特征,了解林分对城市土壤的改良效应,指导城市土壤保育提供依据。选择了刺槐林,女贞榆树混交林,黄葛树女贞混交林、水杉林以及竹林、蒲葵林等6种典型林分类型为对象,通过对林分土壤的机械组成、孔隙度和全氮、全磷、全钾等主要营养元素含量的对比,开展不同林分类型对城市水岸土壤的改良效应研究。研究结果表明:① 6种林分土壤中,女贞榆树混交林土壤的黏粒和粉粒含量最高,分别为7.79%±0.06%和60.01%±0.15%;黄葛树女贞混交林和刺槐林次之;蒲葵林和散生竹林最低。②土壤总孔隙度和毛管孔隙度表现为刺槐林最高,分别为47.41%±0.79%和44.22%±0.87%;其次是女贞榆树混交林 > 黄葛树女贞混交林 > 竹林 > 水杉林 > 蒲葵林。③土壤全氮、全磷和全钾含量均以女贞榆树混交林最高;土壤全氮和全钾的最低含量为水杉林含量,土壤全磷的最低含量则为蒲葵林。综合土壤机械组成、孔隙度和全氮、全磷、全钾等主要营养元素含量的表现看,女贞榆树混交林对城市土壤的改良效应最好。

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.
