摘要
在硬质护岸的生态修复工程中,由于土层较薄,土壤的保水性能成为影响植物生长的重要因素。设计了试验桶和试验池两个试验方案,均在土壤表面覆盖卵石,定期测试土壤含水率。通过比较两个方案含水率的变化规律,总结了卵石覆盖层对土壤的保水性能的影响,结论可以指导硬质护岸生态修复工程的设计。
The water-saving capability of soil is an important factor influencing vegetable growth because the soil layer is thin in ecological restore of rigidity revetment. Two test schemes of test barrel and test pool are designed, the soil with scree and test water content on schedule in both test schemes are analysed. Comparing the change rule of water content in two schemes, the scree cover affects the water-saving capability of soil are proposed. The conclusion of the test can be applied to the design of ecological restore of rigidity revetment.
