摘要:
[目的]针对黄土高原干旱地区生态环境脆弱、景观层次单一的区域现状,探索基于生态设计理论的黄土丘陵区淤地坝景观再造与更新的理念与方法,为黄土丘陵沟壑区小流域环境治理提供借鉴。[方法]以陕西省绥德县辛店沟水土保持示范园北侧淤地坝景观改造设计为例,在现状调研的基础上,进行人工湿地工程改造设计方法研究。[结果]丘陵区淤地坝景观的再造与更新应以生态设计理论为基本指导,对丘陵区淤地坝改造实施自由表面流人工湿地综合工程措施。[结论]丘陵区沟壑地环境治理应综合考虑水土保持、景观生态、旅游观光等多重功能,通过实施低影响开发措施,充分发挥区域环境的最佳生态效益,并兼顾经济效益与社会效益。

Abstract:
[Objective] With respect to the regional phenomenon of ecological environment vulnerability and single stratification of landscapes in loess hilly region, the ideas and ways of landscape reengineering and renovating of check dam based on the eco-design theory were studied in order to provide new thoughts and references for environmental governance.[Methods] The landscape renovation design was located in north of soil and water conservation demonstration garden in the Xindian watershed of Suide County, Shaanxi Province, based on the investigation and analysis of the current status, the researches which focused on the renovative ways of the construction wetland project design were conducted.[Results] The ideas about landscape reengineering and renovating of check dam in the arid area were put forward, simultaneously, integrated implemented measures of free water surface constructed wetlands project for the arid area should be considered and guided by the ecological design theory.[Conclusion] Environmental governance in the arid area gullies should comprehensively consider soil and water conservation function, ecological landscape construction and tourism function, and ensured to produce the best ecological performance, economy performance and social performance by implementing the measures of low impact development.
