Study On Rain Of Small Towns Landscape Planning Based On Green Space Landscape Pattern

Rain landscape planning and design of small town in our country is largely in the traditional design patterns,ignored the thinking of green space landscape system in hydrological environment,caused the hydrological landscape of small town environmental degradation.Rain landscape planning of small towns in China,the problems facing,reference to domestic and foreign advanced technology of Rain landscape planning of small towns,through the integrated use of landscap e,water supply and drainage,the ecological environment,geographical information and related discipline theory,combined with urban geographic information data,drainage pipe network,urban natural disaster situation,etc.,from the Angle of systematic a nd scientific based on green space landscape pattern analysis approach to the study of Rain landscape planning of small towns.This article system elaborated the research background of Rain landscape planning of small towns,content,purpose and significance,and research methods and framework.Rain the influence factors of landscape planning and design of small towns,the respect such as design method collects and analyzes related research results at home and abroad,grasp the domestic and foreign relevant Rain landscape planning of the implementation of the methods,strategies,and development status,etc.,of the systems for small towns of Rain landscape planning and design research materials,innovative research train of thought is put forward.At the sa me time combined with the green space landscape patches,and other related theory,blend in small town green space landscape pattern analysis of Rain landscape planning and design,thus carries on the scientific and effective in small rain landscape planni ng and design.To further improve the urban Rain landscape planning and design level,improve the small town green space landscape environment has important theoretical and practical significance.On the one hand,through the analysis of landscape planning and rainwater utilization at home and abroad related theory research results,further enrich the Rain landscape planning and design theory and method of small towns in our country,the rain water for small towns landscape planning and design method of the innovation provides the theoretical basis;At home and abroad,on the other hand,through the analysis of Rain landscape planning in terms of actual case studies and practical exploration,Rain landscape planning and design to provide practical basis for small towns,Rain landscape planning and design of small towns to offer reference to the decision-making process and the design method.Research using the 3S technology provided by the various maps and field survey data,as a green landscape patches of extraction and classification of data sources.Using artificial ENVI technique in satellite remote sensing image interpretation to extract the green space landscape patches,using ArcMap software as a platform,for assignment patch attributes.Green space landscape pattern by using the methods of digital model analysis decomposition control indexes of Rain landscape planning of small towns,based on researching in the early period of the green space landscape pattern analysis,from the green space,roads,park ing lots,buildings and square four aspects of the subsystems of the comprehensive consideration of rainwater utilization requirements,to explore suitable for small towns of Rain landscape planning and design optimization strategy,provide theoretical sup port for the Rain landscape planning and the method of guidance.And through the case study of Nanxian Rain landscape planning that is based on the analysis of the green space landscape pattern and the implementation process of Rain landscape planning of small towns.Based on green space landscape pattern analysis,this paper studies the landscape pattern index of small cities and towns status quo of water pressure distribution,guiding Rain landscape planning,can be more intuitive understanding of the comprehensive and analyze the present situation of small towns Rain landscape planning for small towns Rain landscape planning and green space system planning of small towns has provided the scientific basis.Innovations in so based on green space landscape pattern analysis,and through the analysis of landscape pattern index of urban drainage pressure impact analysis to guide the Rain landscape planning of small towns,and summed up a set of relatively Rain landscape planning and design strategies and the organic combination of small towns in the case study,can be used as a blend in landscape pattern index Rain landscape planning and design study of an innovative attempt.
