摘要
在水文地质学领域,人们一直非常关注干旱半干旱地区的水文地质和生态地质环境问题.遥感数据以其非接触、全面、精确并具有稳定数据质量的特点,被广泛应用于各个领域.本文利用遥感技术结合地下水数据,依据条件植被覆盖率的概念,研究西辽河流域适宜于植被生长的地下水位埋深.并对不同海拔、坡度范围内植被覆盖率的影响进行了探讨.结果表明,西辽河流域适宜于植被生长的地下水位埋深范围为 2～6m,在 0～200 m的海拔范围内,条件植被覆盖率占 46.23%.坡度在 0°～5°范围内条件植被覆盖率占 80.90%.研究结果对该区域生态环境监测和修复有指导价值,可帮助相关部门实施植被保护和管理.
Abstract
In the field of hydrogeology,people have always been very concerned about the hydrogeological and ecological geological environmental issues in arid and semi-arid areas.Remote sensing data is widely used in various fields due to its non-contact,comprehensive,accurate,and stable data quality characteristics.This article uses remote sensing technology combined with groundwater data,based on the concept of conditional vegetation coverage,to study the suitable depth of groundwater table for vegetation growth in the Xiliao River Basin.And the impact of vegetation coverage within different alti-tude and slope ranges was discussed.The results indicate that the suitable burial depth range for vegetation growth in the Xiliao River Basin is2～6 m,and within the altitude range of 0m to 200 m,the conditional vegetation coverage rate accounts for 46.23%.The vegetation coverage rate accounts for 80.90%when the slope is within the range of 0°～5°.The research re-sults have guiding value for ecological environment monitoring and restoration in the region,and can help relevant departments implement vegetation protection and management.
