研究全球板块边界模型NNR-MORVEL56的建立方法,以及NNR-MORVEL56与NNR-NUVEL1A在板块相对角速率、速率均方根方面的差异;讨论模型中引自PB2002的31个小板块对25个大板块角速率的影响,利用最新的、较全面的全球空间大地测量数据建立实测模型,与NNR-MORVEL56对比进行相关性分析,验证NNR-MORVEL56模型板块划分的合理性。提出借鉴NNR-MORVEL56边界划分方法,进行中国块体的研究。
This paper studies the building method and achievements of the global plate boundary model NNR-MORVEL56,and the differences between it and NNR-NUVEL1 A,with respect to the plate relative angular rate and root-mean-square of the rate(RMS).It then discusses the influence in angular rate of the 31 small plates from PB2002 on the other 25 major plates.Mean while,based on the NNRMORVEL56 boundary,the paper establishes the measurement model by using the latest and most comprehensive global space geodesy measurement data,and it analyzes the correlation with NNRMORVEL56 to test the rationality of the plate division of the model MORVEL56.Aiming at the complicated characteristics of geological structure in China,this paper puts forward some advice referring to the NNR-MORVEL56 boundary dividing method.
