Study on Soil Moisture of Natural Secondary Forests in Eastern Mountainous Region of Heilongjiang Province
摘要
Abstract
The soil water content of different natural secondary forests in eastern mountains of Heilongjiang Province was studied, and the results showed that: ①The soil moisture of natural secondary forests in different terrains declined gradually as the soil depth increased; ②The soil water contents varied most in the depth of 0～10 cm, up to 20.47%. While there were mini-mum difference in the depth of 30-40 cm, merely 8.00%; ③The soil moisture of natural secondary forests in different terrains increased first and then declined from June to September, reaching to the peak of 59.09% in July and dropping slightly in August and September, in which the soil water content of 20-30 cm in Tilia and Quercus mongolica forest was 12.31%; ④High tem-perature was the primary factor leading to the decline of soil moisture in August, but it had less impact on shady slope; ⑤The soil water retention of natural secondary forests mainly depended on the soil structure and porosity status under different terrains condi-tion.关键词
