The low-pressure andalusite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, staurolite-andalusite zone, sillimanite zone and cordierite-sillimanite zone. It is calculated that the P-T conditions are 445～550℃, 0.2～0.6GPa for biotite zone, 480～566℃, 0.54± 0.22GPa for the garnet zone, 601±20℃, 0.8±0.25GPa for the staurolite zone, 540±20℃, 0.32± 0.05GPa for the staurolite-andalusite zone, 640℃, 0.43GPa for sillimanite zone, 740～800℃, 0.4～0.7GPa for the cordierite-sillimanite zone.

黑云母带的变质条件估计在445～550℃、压力在0.2～0.6GPa范围变化；石榴石带温度在480～566℃、压力在0.54±0.22GPa的范围；十字石带范围为601±20℃、0.8±0.25GPa；十字石-红柱石带为540±20℃、0.32±0.05GPa，而利632.4℃、0.785GPa，这个值不是红柱石的稳定范围，这可能是其早期中压变质条件；矽线石带的条件640℃、0.43GPa左右，由于其石榴石中有蓝晶石包体，因此其早期也可能有中压条件的变质；堇青石-夕线石带范围大致为740～800℃、0.4～0.7GPa之间。

Our results indicate that not only the poloidal convection patterns in uppermost mantle have good correlations to surface tectonic motion, but also the toroidal ones reveal important information of their horizontal motion and rotation for the first time. There is a SEE_NWW strong convection zone close to the equator in toroidal convection patterns, which probably correlates with the large_scale shear zone near the equator and is the deep dynamic background of strong earthquake occurrence in this zone. The opposite rotating large_scale convection rolls in the Southern and Northern hemispheres suggest that maybe there is differential rotation between them.

研究结果表明，不但地幔浅部的极型场对流图像显示出了与大地构造运动的相关性并揭示了其深部动力学过程，更重要的是，地幔浅部的环型场对流图像首次为我们认识和理解板块构造的水平与旋转运动提供了重要的信息：环型场速度剖面中在赤道附近存在一条大致南东东—北西西向的强对流条带，可能与环赤道附近大型剪切带的形成相关，进而表明可能是该带强震发生的深部动力学背景；在南北半球存在的旋转方向相反的对流环表明它们整体上可能存在差异旋转。

This paper use for reference the free trade zone development theory both at home and abroad. conjoint to the actual situation of Haikou Free Trade Zone and Macun Port. It use the SWOT theory to analyze the strengths of port's conditions, city's environment, economy potency, city industry basic, opening situation, Boao Asian Forum platform, and air-line right opening. It analyzed the weakness of the un-perfect policy and code, the promoting level of using foreign capital, the mini scale of outer economy, the small size of economy gross, the un-powerful competition, the outer amending invest surroundings, rigidity of foreign exchange control. It also analyzed the opportunities of the incorporate trend reinforce of global economy, ocean economy fast rising, transition of bonded zone to free trade zone. The article point out the threats of Bonded Port and Zone's challenge, the challenge of Guangxi Zhuang Nation Autonomy Zone, bonded zone policy weakening after China joined the WTO, the menace of China-ASEAN Free Trade Area. This paper drew a feasible development strategic for Haikou Free Trade Zone move to Macun Port. It define strategic target emphases and processes.

本文回顾过去14年海口保税区发展的历程，总结成功经验和不足之处，运用国内外保税区发展理论，并结合海口保税区和马村港的实际情况，利用SWOT分析法，分析了海口保税区西移马村港后存在的口岸条件、城市环境、经济潜力、城市工业基础较好、对外开放格局基本形成、博鳌亚洲论坛平台和航权开放等优势，也分析了有关政策法规不健全、外资利用水平有待提高、外向型经济规模较小、经济总量较小、综合竞争力不强、外部投资环境有待改善和外汇管制僵化等劣势，海口保税区也面临着全球经济一体化趋势加强、海洋经济迅速兴起和保税区向自由贸易区转型的良好机遇，认清来自保税港区的挑战和广西的挑战、入世后保税区政策优势削弱和来自中国——东盟自由贸易区的挑战。
