| In the late 1990 s,flood prevention and river reclamation were the key and hot spots in water conservancy construction in China's irrigation areas.Although the river improvement project has ensured urban flood control and water supply security,it is often easy to overlook the balance of water ecosystems and the shaping of cultural landscapes.The experience of large-scale river water conservancy construction is used in ecologically fragile irrigation district water conservancy construction.Excessive drafting and straightening,and pulp and stone revetment have destroyed the original natural beauty of the irrigation district,and also blocked the exchange and integration between human and water.Affected the landscape pattern of the irrigation area,resulting in visual monotonous monotonous,there is no aesthetic taste at all.In the new era of beautiful rural construction and ecological water conservancy construction in irrigation districts,from the perspective of ecological water conservancy project concepts and landscape aesthetics,it is very important and urgent for the ecological landscape design that the irrigation area proposes a unified economic,social,and environmental benefits.This article aims at the harmonious co-existence of human and nature as the development goal,and discusses how to restore the ecological balance,improve the landscape pattern and reflect the cultural landscape in the planning of the Yellow River irrigation district in the North China Plain.Based on the analysis of the natural environment characteristics and status quo of the irrigation area,combined with the research progress in related fields at home and abroad,the theoretical basis of the ecological water conservancy landscape construction in the irrigation area was summarized,and the construction system and construction strategy based on the principles of landscape ecology were proposed.The specific methods and techniques needed in the construction of ecological landscapes in irrigation areas are discussed in terms of the overall landscape layout of the irrigation area,the design of water environment and agricultural and forest landscapes,and the construction of humanistic landscapes.A practical exploration of the landscape design project of the Yellow River Irrigation District in Sanyizhai Village,Lankao County will be carried out to improve the living environment of the urban space in the irrigation area.At the same time,this paper also provides basic research for the theoretical system of ecological landscape construction in irrigation areas.(The irrigated area in this paper refers specifically to the Yellow River Irrigation District in North China Plain)The main research results of the paper are as follows:(1)Explain the important significance and role of ecological landscape construction in irrigation districts for urban construction,analyze the current status of irrigation districts,and interpret the principles of ecological water engineering and landscape ecology,and propose guiding principles for ecological,cultural,and sustainable development,and establish “dotted lines”.The structure of the surface-plaques,corridors,and matrices put forward the construction strategy of "guarantee the balanced ecological balance of irrigation,make full use of resources,build corridors to extend and maintain,and retain the appearance of nostalgia",and introduced the water environment of the irrigation area in detail.The design methods and technical requirements of agricultural and forestry landscapes and cultural landscapes.(2)Combine the actual project,analyze and analyze the local natural and social conditions,geographic landscape,environmental status,etc.,and formulate corresponding design concepts,design principles,design goals,and positioning according to the local irrigation area's environmental characteristics and needs,so as to Comprehensive and multi-faceted governance and planning,based on solving existing problems,building sustainable ecological green corridors and enhancing landscape cultural connotations. |
