| 摘要: |
| 与大多数地处郊野的湖泊湿地一样，荆州崇湖水系存在季节性水量不足、水系地貌结构单一、局部水质较差、栖息地生境匮乏等突出问题。从水环境的物质要素组成、整体空间形态格局、动态演化规律出发，通过研究湖泊湿地水文过程原理，归纳出水量、水形态、水质和水域栖息地4个影响水文过程的景观系统因素，并提出了基于风景园林学途径的水环境修复框架。以崇湖为例，依据修复尺度将景观功能及设计方法整合到了湿地水环境的保育体系当中：在宏观层面，重新划分、建构区域水系网络，优化水系空间形态结构；在中观层面，疏通周边水系，重建水量收支平衡；在微观层面，辅助建构局地净水生境，优化栖息地条件。以期为郊野型湖泊湿地水环境保育研究提供参考，为修复工作的开展提供思路与借鉴。 |

| Abstract: |
| Like most lake wetlands located in the suburb, Chonghu Lake water system has some problems such as seasonal water shortage, poor water quality, single landform structure and lack of biological habitat. This paper starts with the study of the composition of material elements in the water environment, the overall spatial pattern, and the dynamic evolution rules of water system. Based on the basic principle of the hydrological process of the lacustrine wetland, this paper summarizes four influencing factors of the lake system that intervene in the hydrological process, such as water quantity, water quality, the shape of lake, and water biological habitat, and then puts forward a water environment restoration framework based on landscape approach. This paper, taking the Chonghu lake as an example, integrates landscape function and design method into the water environment restoration system according to the restoration scale. At the macro level, it is proposed to redistrict and construct regional water network and optimize the spatial morphology and structure of water system; at the meso level, it is proposed to dredge the surrounding water system and restore the balance of water quantity; at the micro level, it is proposed to build local water purification habitat and improve the habitat conditions. This paper is expected to provide references for research on conservation of water environment of lake wetlands in suburb and provide instructions for the development of the restoration work. |
