本文以东南沿海地区为对象，研究了区内强震活动的时、空、强分布演化特征，综合分析认为，在目前新的地震活跃期中，广东省的强震形势值得注意，尤其在2000年前后，历史上未发生过强震而又具备发生强震条件的地区。通过对构造背景、强震分布、震中迁移等分析提出的广东中部及其近海地区更应注意。

Nov. mainly inhabits those channels such as mahuang channel、gari channel、bori channel、heping channel and dengchi channel. So it belongs to the distribution area extremely narrow type. From May to October 2005 and May to August 2006, 671 specimens collected were used for studies on the reproductive strategies such as reproduction time, spawning type, the ratio and the fecundity, and gonad development and characters of early life history. The main results are as follows: 1.Every year speaking of spawning season the male"s is earlier than female"s slightly.

Nov。仅分布于宝兴河支流东河盐井以上河段，主要分布在蚂蝗沟、嘎日沟、波日沟、和平水域及邓池沟，属于分布区极其狭窄的种类。2005年5月—10月和2006年5月—8月共采集671尾标本，运用常规生物学指标的测定分析法和性腺的组织切片法，以及对成熟亲鱼人工授精获得的胚胎在立体显微镜下活体观察，研究其繁殖期、产卵类型、性比和繁殖力等繁殖策略及性腺发育和早期发育。

By the field survey which lasting a period of 3 grown seasons and by the means of remote sense and geographic information system, we ascertain the present vegetation pattern of Hunshan-Dake sand land, find out vegetation distribution principles on the different scales in the same time . From west to east, with the increasing of dry degree, the type of plant community changed form the xeric to the mesic. The vegetation of Sand land shows the characteristic of the zonal vegetation, but dont consistent with the traditional diversification principle. The vegetation of the middle part displays a high differential characteristic, which compresses the longitudinal zonation at a certain extent. So we can say that sand land vegetation is semi-zonal.

通过对浑善达克沙地历时三个生长季的地面考察并应用遥感及地理信息系统等手段，确定了浑善达克沙地植被分布现状及浑善达克沙地植被在不同尺度下的分异规律：由西向东，沙地植被随着干燥度的降低，由旱生群落为主的区段递变为以中生群落为主的区段，表现出具有一定的地带性植被特征，但与传统的地带性植被的递变规律不相一致，沙地中段的植被表现出了高度的特异性，在一定程度上压缩了植被的经向地带性，表现出沙地特有的地带性分布规律，所以认为沙地植被是一种半地带性植被。

The formation process of different surface topographies and their micrographic characters in low density polyethylene was studied in this paper.

At the same time, the distribution mode of the strand shallow lake and the delta deposition system have been established in this region. The research on type and distribution regulation of subtle trap combining with geologic strata structure indicates that the south slope belt, ditch valley belt, Guangbei slope break and southwest of noselike conformation belt are the more advantageous belt to find subtle trap.

在层序地层格架内，通过古地貌研究和沉积体系研究，识别出低位沟谷带和坡折带等控制沉积的两种地貌，建立了本区滨浅湖沉积体系和三角洲沉积体系的分布模式，结合地层结构特点，对隐蔽圈闭类型及分布规律进行研究，指出南部斜坡带、沟谷带、广北坡折带及鼻状构造带西南端是寻找隐蔽圈闭的有利区带。

Based on the relationshiphydrocarbon distribution between formation condition of S_(2+3) oil layer in the west slope region, the resultshows that hydrocarbon formation and distribution were mainly controlled by trap development,relationship trap between the room place of oil-gas migration pathway, convergence area of centrifugalflow and endocentric flow, etc. Oil-gas accumulation period is the end of Nenjiang formation sedimentation,Mingshui formation sedimentation and the early of Palaeocene.

根据西斜坡区萨二、三油层油气分布与油气成藏条件关系综合分析得到，西斜坡区萨二、三油层油气成藏与分布主要受圈闭发育、圈闭与油气运移路径空间位置关系、向心流与离心流交汇区等因素的控制，油气成藏时期除嫩江组沉积末期，还有明水组沉积末期—古近纪初期。
