Ecological water requirement by vegetation in a river basin of Haizi, Liupanshan Mountain
摘要
Abstract
On the basis of Liupanshan Mountain Haizi basin of meteorological data, using the method of Penman and Thonrnthwaite integrated the vegetation quantity of potential evapotranspiration is obtained, further consideration of soil water content and vegetation types to calculate the vegetation in the growth period minimum ecological water requirements and ecological water requirement. The results show that the minimum ecological water requirement 326.11×104 m3, Liupanshan Mountain Haizi watershed vegetation, minimum ecological water demand rich quantity of 3.17×106 m3; 573.54×104 m3 suitable for ecological water demand, appropriate amount of ecological water demand rich 1.49×106 m3. Rainfall is able to satisfy the basic growth of existing vegetation; Generally can meet suitable vegetation ecological water requirement, better meet the grassland ecological water requirement, the grass grew well, basically meet the normal growth of shrubs, nursery, other woodlands water requirement, and can’t meet the arbor normal growth water requirement. For large area planting vegetation, optimize planting structure.关键词
