Comprehensive urban climate environment assessment method integrated with multiple-source remote sensing and climate environment information

Abstract

The invention discloses a comprehensive spaced and visualized urban climate environment analysis and assessment research method under multiple seasons and environmental elements, and belongs to the research of the urban climate environment application field. According to the analysis and assessment method, complex topography effects and air-sea-land interaction are fully considered, four-season urban climate environment and urban planning information are integrated, urban climate environment problems at present and under planning backgrounds are shown mainly by two-dimensional graphics, and planning suggestions for the urban climate environment problems at various seasons are proposed, so that urban thermal pollution and air pollution problems can be effectively relieved. The urban climate environment assessment and analysis method is comprehensive, real-time, easy to acquire and use, and relevant achievements of the method can be regarded as the important decision-making basis of the urban planning, urban climate and ecological human habitat environment construction field.

Description

technical field [0001] The patent of the present invention relates to the application field of urban climate environment, especially a spatialized and visualized comprehensive analysis and evaluation method for urban climate environment aimed at multi-season and multi-environment elements. Background technique [0002] At present, urbanization is booming all over the world, and effective urban climate and environmental information and planning measures are needed to alleviate urban climate and environmental problems, which provides a new opportunity for urban climate and environment research. Urban climate environment analysis and assessment work is an information analysis and assessment tool that integrates the physical characteristics of the urban underlying surface, climate environment elements and environmental problem elements. It uses two-dimensional space to display urban climate environment phenomena and urban climate environment problems, and combines Make scientifi...

Problems solved by technology

[0003] At present, the analysis and assessment methods of urban climate environment only consider summer or winter and summer seasons in terms of seasons, lacking a comprehensive analysis of urban climate environment in four seasons; most of the environmental issues in the assessment only consider the urban heat island problem, and even air pollution is seldom considered Consider environmental issues such as haze that have only been paid attention to in China in recent years; in obtaining atmospheric and thermal environment information, ground station monitoring data are mostly used, but there is a lack of comprehensive application of multi-source remote sensing retrieval information; in monsoon climate regions due to The complex physical environment and rapid urbanization have formed the characteristics of urban climate and environment with obvious seasonal changes. The urban climate and environment research that only analyzes and evaluates a single summer season or a single environmental problem at the scale of the study area can no longer meet the needs of these urban development plans. need

Therefore, the method of comprehensive analysis and evaluation of the urban climate environment combined with multi-season and multi-environmental elements in the study area and its background area is suitable for the analysis and evaluation of the urban climate environment in the complex physical environment and multi-environmental elements of the monsoon climate area. However, there is a lack of research on these
