中国滑坡、泥石流灾害的时空分布特点

环境、生态、灾害是当前人类所面临的重大紧迫问题，同时也构成当代科学研究的最前沿课题之一。我国滑坡和泥石流除在空间表现出明显的分布特征外，在时间上也呈现一定的规律性特点。表现出滑坡、泥石流灾害的宏观动态特征不仅有其特殊的波动特性，而且还显示一定的周期性特征。

The Temporal and Spacial Distribution of Landslide and Debris Flow Disasters in China

Environment,ecology and disaster are the three pressing problems facing mankind nowadays,and meanwhile they constitute the leading subjects in current scientific research.Apart from the obvious distributional patterns,landslide and debris flow in China also shows certain regularity in time landslide and debris flow disasters,in other words,not only have shown macroscopic features,but have also shown certain cyclical character.
