In order to supply theoretical basis for the generalization and management of Larix leptolepis, the effects of meterological factors on the growth quantity of Larix leptolepis were studied by step-by-step regression and grey relation analysis based on the data of 15 analytical stem and meterological data of the lastest 20 years in LuanChuan.

Assisted by DNA2.0 and Gene2Oliga software, we optimized the codon usage and secondary structure of RNA and induced enzyme sites Cla I (237 site) and Pst I (475 site) into the gene. In the first step, fragments F1 (237 bp), F2 (238 bp) and F3 (422 bp) were separately synthesized by assembly PCR. In the second step, fragments F1, F2 and F3 were separately digested by Cla I and Pst I, and then ligated into a full length lipA gene.

首先在DNA2.0和Gene2Oliga软件辅助下对lipA基因密码子及RNA二级结构进行优化并引入Cla I(237位)和Pst I(475位)酶切位点；通过组装PCR分别合成lipA基因的各片段F1(237 bp)、F2(238 bp)和F3(422 bp)；通过该基因内的Cla I和Pst I限制性酶切位点连接成完整的全长lipA基因。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。
