摘要
利用辽西地区16个气象台站30年（1971年～2000年）的整编温度资料，时辽西地区主要热量资源的现状和变化进行分析，结果表明：在全球变暖的大背景下，辽西地区热量资源变得更加丰富，20甘纪90年代年平均气温升幅达0．56％，≥10℃积温30年间增加了158．5℃。借助GIS技术和数学模拟技术，时辽西地区部分重要的热量资源条件进行栅格化，构建了6种气候要素的小网格推算模型，经过小地形订正，生成为100m×100m空间高分辨率的栅格数据库和相应的专题数字地图，以满足多方面的需求。
The actuality and variability of the main thermal resources in west Liaoning province was investigated based on analysis of 30 years temperature data from 16 meteorology stations （ 1971 - 2000）, The result suggests that the main thermal resources in west Liaoning province were more abundant than before under global warming condition, which was featured by increasing temperature. The increasing magnitude of mean annual temperature had reached 0.56 ℃ in 1990s due to global warming. The increasing magnitude of temperature had significant differences in different seasons and it varied significantly from zone to zone, In winter, the increasing magnitude of temperature was the highest （the mean value of increasing magnitude was up to l, 14℃）, However, the increasing magnitude of temperature was the lowest in summer （the mean value of increasing magnitude was only 0.29 ℃ ）. The accumulated temperature ≥ 10℃ in west Liaoning province had increased 158.5℃ during the past 30 years. Based on the effect of geographical factors on the main thermal resources in west Liaoning province, we estimated the simulation method of the fine resolution-spatial distribution of the main thermal resources by applying statistical software of SSPS. 10. By applying geographical information systems and databases in association with geographical factors, such as longitude, latitude and altitude, we simulated the main thermal resources spatial distribution in west Liaoning province. Finally, the fine resolution （ 100 m× 100 m） maps of the thermal resources spatial distribution in west Liaoning province have been drawn. Moreover, the thematic maps relevant to thermal resources have also been mapped. These digital maps at fine resolution will provide the basic data and a research platform for ecology, geography and environment science.
