| 摘 要： | 采矿对环境具有一定影响。辽西半干旱区和辽东半湿润区野外定点观测结果表明:矿区气温,夏季高于对照2℃～7℃,春秋季节低于对照区。矿业弃物堆(岩土)含水量低于对照6～11个百分点,在干旱期,岩土含水量仅为植物萎蔫含水量甚至更低。矿业弃物堆的蒸发量高于对照1～5mm,但矿区的空气相对温度却明显低于对照。由此说明,矿区环境条件迥别于周边环境,更趋于沙漠区的自然环境。

| Abstract: | Paying attention to and ensuring the security of terrestrial ecology in ecologically vulnerable areas are essential to realizing sustainable utilization of regional land resources. The concept and theoretical basis of securing regional terrestrial ecology in ecologically vulnerable areas are advanced on the basis of analyzing factors of the ecological management system. A new method, based on remote sensing (RS) and geographical information systems-environmental impact systems (GIS-EIS) and involving evaluation, precaution, simulation and optimization of the system, is advanced. The final result of the research is a comprehensive system for terrestrial ecology management in ecologically vulnerable areas, which contributes to progress in the field of securing regional ecological environments. |
