| 摘 要： | 研究了大连市石门山丘陵区灌木丛、针叶林和阔叶林三种不同植被类型条件下的浅层土壤水分和养分状况。结果表明:土壤含水率变化在10%～20%之间,阔叶林样地土壤含水率全年波动较大,灌木丛样地次之,针叶林最为稳定。土壤养分含量的变化除速效磷表现为灌木丛阔叶林针叶林外,有机质、速效钾、硝态氮和铵态氮都表现为阔叶林灌木丛针叶林。从空间角度来看,各样地山顶、山腰和山底土壤水分和养分变化不尽相同,但各自差别并不明显。不同植被类型对土壤养分含量存在显著影响,其变化基本符合随植被演替阶段提高而升高的规律。总的来看,植被恢复对土壤质量有着明显的改善作用。

| Abstract: | This paper reported the soil moisture and soil nutrient contents from a study carried out in different vegetation types of Dalian city.The results showed that the soil moisture rate was between 10 %-20 %,and it fluctuated most obviously in broadwood land,next was in shrubbery and the most stable one was in taiga.Despite the order of AP content being shrubbery > broadwood land > taiga,the other soil nutrient contents were all in the order of broadwood land > shrubbery > taiga.The soil moisture and nutrient c... |
