摘要
宁夏中南部地区在水源涵养和水土保持方面具有重要的生态地位。近年来,该地区植被覆盖、水土保持和荒漠化治理取得明显成效,环境质量一直处于较好水平,部分资源利用水平较高,但宁夏中南部的偏北部地区生态治理任务仍然艰巨,部分区域和领域的污染问题仍然突出,资源紧约束和粗放利用并存现象仍然严峻。针对宁夏中南部地区自然人文地理特征,本文分别从生态、环境、资源方面提出治理和保护重点,并建议应坚持以健全水系统为核心的生态环境保护总体思路,即通过水生态功能的恢复和完善,促进水资源量的增加,继而通过水生态和水资源的改善,提高水环境容量,进一步健全水生态、资源、环境系统,提升自然生态系统整体效能。
The central and southern areas of Ningxia have an important ecological status in water and soil conservation.In recent years, significant results have been achieved in vegetation coverage, soil conservation, and desertification control.The environmental quality has always been at a good level.Some resources have been used at a relatively high level.However, the tasks of ecological management in the northern part are still arduous, pollution problems in some regions and fields are still prominent, and the pressure of tight resource constraints and extensive utilization is still severe.Several ideas for promoting the ecological and environmental protection of central and southern Ningxia have been put forward, around the local characteristics of physical and cultural geography.Especially, water system is the core.Through the restoration and improvement of water ecological functions, the increase of water resources is promoted, and then through the improvement of water ecology and resources, the water environment capacity is increased, and then through the improvement of water ecology, resources and environmental systems, the overall efficiency of the natural ecosystem is enhanced.
