珠江三角洲六千年来的发展模式可概括为如下三个方面:1.多次分汊,多级发展;2.沙洲合并,河汊由繁到简;3.左汊萎缩,右汊发展,整体偏右.这种发展模式,是在本地区动力条件、基底地形、构造运动、侵蚀基面变动以及科氏力等多因素相互作用的综合产物.研究珠江三角洲的发展模式,在理论上和实践上都有重大意义,可为预测珠江三角洲的发展趋势提供科学依据.例如,掌握“沙洲合并,由繁到简”的自然规律,就有可能较深入地论证在治理中所采取的“联围”措施;而搞清楚“左汊萎缩,右汊发展”的规律,则有助于水利建设和航运的改善,选择富有生命力的右侧汊道作为主要排洪道和航道.
The pattern of development in the Pearl River Delta over the past six thousand years can be summarized as follows: 1. multiple points of division and multi-level development; 2. sandbar mergers and the river ridges from simple to simple; 3. shrinking leftists and developing rightists; As a whole to the right.This development model is a comprehensive product of multi-factor interaction such as dynamic conditions, basement topography, tectonic movement, erosion basal changes and Coriolis force in this area.Studying the development mode of Pearl River Delta, in theory and It is of great significance in practice and can provide a scientific basis for predicting the development trend of the Pearl River Delta.For example, if we grasp the natural law of “sandbar consolidation, from simple to simple”, it is possible to prove in more depth the “ Wai ”measures; and figure out the“ Zuo Xi shrinking, right development ”rule, it is conducive to the improvement of water conservancy construction and shipping, the choice of the lifeblood of the right side as the main flood and waterway.
