基于Landsat7ETM+的青岛地区热岛效应反演及分析

用水源热泵技术，将矿井回风、矿井水、洗浴废水、冷却水（风）中的低品位废热转变为供热热能。该热泵热回收技术系统可靠、经济效益好，可达到节能减排的目的。该文分析了矿井系统中的废热类型和应用原理，给出了矿井回风、矿井水、洗浴废水、冷却水（风）废热回收量的计算方法，并分析了山东济宁梁宝寺煤矿矿井废热回收供热系统设计实例。认为该技术的应用为矿区提供了生产、生活必备的热源和热水，节约了生产成本，保障了煤矿企业的绿色生产，改善了矿区周围的生活环境。

Inversion and Analysis on Heat Island Effect in Qingdao Area Based on Remote Sensing Technology

By using two different remote sensing satellites in Qingdao area from LandsatCD*2]7 ETM+ and related meteorological parameter data, using single window method and radiative transfer equation method, temperature retrieval of remote sensing datas from two different images has been carried out. Through analysis on NDVI, vegetation coverage, spectral analysis, correlation analysis, impervious surface and differences of underlying surface, combining with local environment, discussing the performance of urban island, the temperature level of the distribution and transfer trend, it is concluded that urban island effect is significantly in research area. The intensity distribution has close relation with industrial and residential expansion. Accompanying with the process of urbanization, it will transfer to connection part of the urban and rural areas.
