The Research On The Aird Area Typical Oasis Land Surface Temperature Retrieval And Its Spatial Distribution

Oasis as a unique and very important component unit arid region in the aridnorthwest China, is a very special natural landscape and ecological landscape, themajor geographic carrier of the people's production, life and work who is living in theoasis region. Due to desertification, the drought speed compared more than20yearsbefore becoming faster and faster. The deterioration day by day of the ecologicalenvironment, ecological and environmental issues in all aspects become a seriousthreat to people's living environment and quality of life. Summing up the aboveproblems at this stage, how to protect the ecological environment in the best way, howto maintain the sustainable development of oasis in all respects become a veryimportant aspect of arid oasis research. The existence of oasis in the arid andsemi-arid regions at all times strictly receive restrict of the entire system and the oasesand desert system composed of a variety of energy and different forms of materialflow constraints. Xinjiang region is northwest China's largest province and wheredistributed many arid areas oases, the oasis economy is a major component of theeconomy of Xinjiang, research oasis in the Xinjiang region, we first have to study theenergy flow and system of the oasis and the surrounding mountain desert region partsof the mechanism of interaction. An important component of the land surface energycan be expressed in large part oasis and the energy of the system as a whole, so westudy the land surface temperature is the important part of studying the surface energy.In this study, using the remote sensing technology, land surface temperature asthe indicator which can be expressed surface energy to study the interaction of theoasis energy and the oasis system including desert and mountain. The main sections ofthis paper is organized as follows?Chapter1: Introduction, introduces the research background and significanceof the study purpose and content, and in the collection of a large number of domesticand foreign researchers information associated with this study also introduced theresearch status of the study at home and abroad.Chapter2: The general situation of study area and research necessary datapre-processing. This study took the typical Weigan-Kuqa River delta oasis as theresearch area then introduce the necessary data and data sources, simplypre-processing the research data. Chapter3: This chapter is one of the important chapters in this paper, is the landsurface temperature retrieval. Land surface temperature inversion method and a briefdescription of these methods, first introduced the required parameters, one of the mostimportant parameters for a more detailed description is land surface emissivitycalculation method and calculation process.Take the Qinzhihao single-windowalgorithm for land surface temperature inversion and briefly analyse the inversionresults. Finally, the study of remote sensing information extraction?first determine theremote sensing classification system and then use supervised classification inmaximum likelihood method,classify the study area divided into seven land use typesof information extraction,Finally process the classification accuracy evaluation.Chapter4: Analysis of the spatial distribution of land surface temperature.Firstly calculated the average temperature of the land surface temperature and thenanalysis the result.After that perform profile analysis, Take the Yuejin Reservoir ascenter, East and West profile analysis to identify the characteristics of the section thefinal phase singularity analysis with ENVI make a different surface temperaturediagram of the surface temperature distribution analysis.Chapter5: Remote Sensing Retrieval impact factor affecting the land surfacetemperature analysis, first remote sensing retrieval of land surface temperature mapswith land use map using ArcGIS spatial analysis overlay analysis three years theaverage temperature of various types, to analyze the land use types with therelationship of the surface temperature. Then calculate the study area NDVI and thenuse dimidiate pixel model were calculated in the study area vegetation coverage, tomake the surface temperature scatter plots, vegetation coverage and analysis ofvegetation coverage surface temperature relationship.
