Abstract


Surface temperature in the ground - gas interaction process plays an important role, is a key parameter in the global change research, comprehensive evaluation model of sustainable development and global change, the change in status is also a measure of the quality of the environment and social and economic development The policy of a very important criteria. With the accelerated process of rural industrialization, rural areas of the surface temperature distribution to be significantly affected. But the surface temperature studies are mostly concentrated in the urban areas, especially in metropolitan areas, is relatively rare for the predominantly rural county region. The use of remote sensing technology to estimate surface temperature is simple, fast, and able to obtain a continuous range of surface temperature, time synchronization is better, has incomparable superiority of the traditional methods of observation, and gradually become an important method to obtain surface temperature. Remote sensing technology means choose Gongyi City, Landsat TM images in 1988 and in 2006, Terra / ASTER images of the study area as the main data source, combined with other geographical data of the study area, the integrated use of a variety of geospatial information The technology for the surface temperature of the rural areas and rural industrial development relationship, and obtained the following main results: (1) the reasonableness of the use of different remote sensing data enables more accurate and quick to carry out research work. This article using ASTER data inversion of surface temperatures in the comprehensive use of the 3 ASTER data sub-system data and MODIS data and ASTER Spectral Database data for surface temperature inversion, ideal results. Landsat TM data using the single-window the algorithm temperature inversion results can meet the requirements. (2) analysis of the results of the inversion temperature show that the surface temperature has increased with the development of rural areas, and ultra-high-temperature region are in good agreement with the distribution of the industrial park. (3) changes in land cover types will change the spatial distribution of surface temperature, while the development of the rural areas of construction land increased significantly, and will raise the surface temperature. (4) in the same surface conditions, low level of industrial development phase of the industrial production of the surface temperature does not significantly higher level of industrial development, industrial production will surface temperature distribution significant impact, with the The significant increase in industrial output, the upward trend in the surface temperature. The results of this study show that the industrialization of rural areas, has a significant effect on the surface temperature and the surrounding environment; With the increased range of remote sensing data source, improving the resolution of regional surface temperature inversion can get more reliable results; use of geographic spatial information technology to study the feasibility of the rural economy, to achieve the accuracy requirements of the research work, and make research more convenient.
