近年來,隨著各種生態(tài)問題和污染的日益嚴重,河流保護的研究逐漸成為熱點問題。本文在對河岸帶的涵義、結(jié)構(gòu)功能、管理保護和研究手段等方面詳細闡述和探討的基礎上,指出河岸帶是河流生態(tài)系統(tǒng)中重要的紐帶,是水陸交錯區(qū)域的生態(tài)屏障,發(fā)揮著重要的功能和作用。河岸帶適宜寬度的確定是發(fā)揮河岸帶效益功能和保護河流生態(tài)系統(tǒng)的關鍵。本文主要研究了以下幾個方面內(nèi)容:一是在前人研究的基礎上,提出河岸帶適宜寬度優(yōu)化模型;二是闡述了GIS的發(fā)展和應用,指出GIS空間分析與河岸帶適宜寬度優(yōu)化模型的耦合是確定河岸帶寬度的有效手段;三是以云和縣安溪河為研究對象,基于GIS空間分析功能,確定了安溪河不同寬度要求的河岸帶。通過研究,取得了以下主要成果: (1)在前人研究的基礎上,結(jié)合河岸帶寬度限制條件,提出河岸帶適宜寬度的多目標優(yōu)化模型。 (2)以云和縣安溪河為研究對象,通過GIS空間分析與優(yōu)化模型間的耦合,得到不同寬度要求的安溪河河岸帶。 (3)與現(xiàn)狀對比分析,目前規(guī)劃建設的河岸帶不能滿足適宜寬度的要求,還應在原有河岸帶的基礎上增加河岸帶的寬度。 |

In recent years,with increasingly serious of every king of ecological problem and contamination,study of rivers protection has gradually became a hot discussion.On the basis of detailed description and discussion of the definition of riparian zone,structural function,management and protection,study method etc, the article points out that the riparian zone is an important link in river ecosystem and ecological barrier of amphibious staggered area, and plays a very important function and role. The determination of the appropriate width of the riparian zone is the key factor to exert the riparian zone beneficial function and protect river ecosystem.This text mainly studied several aspects as following:the first one is putting forward the appropriate width optimization model of riparian zone on the basis of previous studies;the second is to expound the development and application of GIS and points out that it is an effective measure to ensure the width of river bank with the coupling of GIS spatial analysis and the appropriate width optimization model of riparian zone;the third is determining the anxi river riparian zone of the different width requirements based on GIS spatial analysis function,taking anxi river in Yunhe county as research object.Through the research,we have obtained the following main results: (1)on the basis of previous studies,combined with the limit conditions of the zone width,the text put forward multi-objective optimization model of appropriate width of the riparian zone. (2)Taking anxi river in Yunhe county as research object,the text gets the different width requirements of anxi river bank through the coupling between the GIS spatial analysis and optimization model. (3)Compared with the status contrast analysis,the riparian zone, which plans to construct nowadays,can not meet the requirements of appropriate width,it should increase the width of the riparian zone on the foundation of the original riparian zone. |
