Vietnam worries that dwindling water volumes will aggravate the problem of sea water intrusion and salination in the low-lying Mekong Delta, where climate change and sea level rise threaten to inundate large areas of productive farm land and displace millions of people by the end of this century.

越南忧心的是，气候变化和海平面上升本来已经威胁着大量耕地，在本世纪末可能导致过百万人的流离失所，而水量的减少将加剧湄公河下游地区海水入侵和盐化问题。

The objective of this study was to (1) explore the environmental, cultural, and hydrologic characteristics for sustainable development of San-Bu-Keng Creek watershed in Shangan area, Shuili Township, Nantou County,(2) investigate factors of causing debris flow such as terrain, geology, hydrology, land use,(3) evaluate the implemented watershed conservation and management strategies and suggest necessary improvements, and propose suitable land uses for sustainable development.

三廍坑溪集水区遇强度高、总量大的暴雨常发生土石流灾害，常造成下游上安社区发生屋毁人亡之惨剧。1996年贺伯台风、1999年的921地震造成水里上安地区溪流集水区源头裂缝、土层松动、坡地崩坏，其后2001年的桃芝台风暴雨更在三廍坑溪造成土石流灾害，计有死亡失踪17人，田园流失近百公顷，房屋全倒26户、半倒29户。造成灾害的原因包括陡峭地形、松散地质与台风暴雨等自然因子及滥垦滥伐，占用河道等不当土地利用。

The survey was made in Xijiang River from 2005 to 2008. Ninety species belonging to 13 orders, 29 families and 75 genura were collected from 6 sampling spots. Eight species including Takifugu vermicularis, Rasbora steineri and Silurus gilberti were newly recorded in Xijiang River.

2005-2008年对珠江下游西江江段6个采样点进行鱼类多样性调查，共采集鱼类96种，隶属于13目29科75属，辐斑虫纹东方鲀、南方波鱼、西江鲇等8种为西江新记录鱼类。

To prepare recombinant fox growth hormone, we amplified its cDNA from silver fox pituitary tissue by RT-PCR and cloned into yeast shuttle vector pPIC9K down stream of α-factor signal peptide sequence by SnaB I and Not I restriction sites. The recombinant secretion vector pPIC9K/fGH, linearized by Sal I, was transformed into histidine-deficient Pichia pastoris strain GS115 by electroporation.

为制备重组狐狸生长激素，采用RT-PCR方法，从银狐垂体中扩增fGH cDNA基因，利用SnaB I和Not I位点将fGH基因插入到酵母分泌型表达载体pPIC9K中α-因子信号肽的下游，构建成fGH基因的酵母分泌型表达载体pPIC9K/fGH，载体经Sal I酶切线性化后，通过电转移将线性化的pPIC9K/fGH转化到组氨酸缺陷型酵母宿主菌GS115中。

ARC1(arm repeat containing 1 ) is a very important downstream protein factor in sporophytic self- incompatible signaling process. It is made up of arm repeat domain, U-box domain, leucine zipper domain/ coiled-coil domain, one nuclear localization signal and two nuclear export signal, arm repeat domain and U-box domain are main functional domain.

臂重复蛋白ARC1(arm repeat containing1，ARC1)是孢子体型自交不亲和信号传导途径下游非常重要的蛋白质因子，由臂重复结构域、U-box结构域、亮氨酸拉链/卷曲螺旋结构域、1个核定位信号和2个核输出信号组成，其中臂重复结构域和U-box结构域起主要功能。

O PSII supercomplex was formed in the plant grown in iron depletion solution. After treatment with NO, all of the above injuries of plant due to iron deficiency were reverted, such as the increase of active reaction center of PSII, the reconnection of PSII with antenna, the increased electron transport rate, the increased photochemical fluorescence quenching and the reduced non-photochemical fluorescence quenching.

O处理后，植物受到的所有缺铁损伤都得到恢复，有活性的PSII反应中心数量增加，与天线的连接恢复完好，电子传递效率增高，同时叶绿素荧光的光化学淬灭增多，非光化学淬灭降低，表明PSII下游的电子传递体也得到很好的修复。

A reduction in groundwater levels and a concomitant increase in soil salinity have reduced vegetation in lower reaches of the river. Tamarix ramosissima is one of the dominant plant species in this riparian system.
