摘要
介绍全球板块边界模型———PB2002的研究方法及其取得的成果。PB2002模型以海洋板块研究为主,在确定中国及周边地区边界时对中国地学界的研究成果参考很少。由于中国大陆地区地壳运动的复杂性,导致国内板块边界划分方法多样,考虑到边界模型多为小比例尺图或示意图的现实,提出了建立中国构造地块数字化边界模型的设想。思路是:针对不同的板块划分方法,分别建立相应边界模型。
Plate tectonic models have developed successfully for a long time, but there are no generally-accepted standard references on plate boundary locations worldwide. Peter Bird gives a model of present plate boundaries on the Earth in digital form, based on sources in the literature. The paper presents the PB2002 given by Peter Bird and his research method for this model and results briefly. The establishment of PB2002 refers hardly any geoscience research of Chinese scholars in Chinese regions. Considering the complexity of lithosphere motion in Chinese regions, there are several methods for dividing the plate boundary according to different hypothesis. In addition, considering that the plate boundary model are given in the form of small-scale maps or sketchs, the paper brings forward some thoughts on establishing plate boundary model in Chinese regions.
