南通市海岸带资源开发和体会

南通市海岸线长205.9公里,沿海县属乡、镇、场48个,堤内土地150万亩(包括建国以来围垦的42.8万亩)。其中可耕地为89万亩;堤外负2米以上滩面141.7万亩。近几年来,根据中央改革、开发、搞活经济的方针政策和现代科技发展的新形势,为把资源优势尽快地转变为经济优势,建成具有海岸带特色的、以面向国外市场为主的、综合性商品基地,坚持了贸、工、农的路子,采取了边试验、边开发的步骤,目前已经进入一个全面性开发的新阶     

我国的鱼类细胞核移植??

鱼类作为水产养殖业的一大支柱品种 ,其良种培育对提高鱼类产量至关重要。我国是鱼类养殖历史最悠久的国家之一 ,向来重视应用生物技术对养殖品种进行改良 ,其中最好的例子之一就是利用细胞核移植技术来创造鱼类优良品种。即使在生物技术不断发展的今天 ,这一细胞核移植技术在鱼类新品种培育方面仍是一项很有潜在应用价值的技术。特别是把细胞核移植技术与现代生物技术相结合 ,有望创造出具有巨大经济价值的鱼类新品种。１我国鱼类细胞核移植的成果细胞核移植是一种应用精细的显微操作 ,将一种动物的细胞核移植到同种或异种动物的去核成熟卵…

烟威渔场盐度预报及分析

本文以我国北黄海的烟威渔场为研究对象,采用优选因子场预报模式,对盐度的时空变化进行预报试验。文中对所采用的统计预报方法,作了简要介绍。对影响本海区盐度变化的显著因子及预报结果作了初步分析。预报试验表明:预报的总体平均绝对误差为0.27‰,预报相对误差在18％左右,预报误差小于0.5‰的站数占总站数的85％,预报趋势与实测资料基本一致。

CASE ANALYSIS OF SEA LEVEL CIRCULATION FOR THE ATMOSPHERE OF LOW LATITUDES IN MID-SUMMER

In the light of the sea level synoptic charts from July to August for 1975-1978, we obtained more observed records of low latitudes by using the analysed stream and temperature-moisture field (or so called energy field θe field and θse field), the main characteristics of these fields in the period of multi-typhoon genesis and of typhoon interval in the mid-summer are studied.Finally, it should be pointed out that the position of the typhoon genesis and the typhoon track are generally consistent with the low temperature-moisture region of the sea surface as well as with its tendency, so that a valuable information is obtained for the forecast of the typhoon track.     

GEOCHEMICAL CHARACTERISTICS OF INTERSTITIAL WATER OF THE BOHAI GULF

This paper discusses the geochemical characteristics of the interstitial water of the Bohai Gulf, where the main salt contents (K+, Na+, Ca++ Mg+ + , C1-, HCO3-, SO4-) in 55 sedimentary layers of 13 cores (3-4 m in length) and those of bottom seawater have been determined and the exchange capacity and exchange cations (K+, Na+, Ca++, Mg++) of the layers analysed (see Fig. 1)Fig. J. The stations of core samplings in the Bohai Gult.     

AN ECOLOGICAL STUDY OF BENTHIC ORGANISMS IN THE NEARSHORE WATERS TO THE WEST OF TAIWAN STRAIT

In seven cruises on benthic organisms in the nearshore waters(>50 m) to the west of the Taiwan Strait(23°20''-25°54''N,117°11''-119°58''E) in 1961-1964,altogether 189 stations of quantitative grabbing and 33 stations of qualitative trawling were made.
Altogether 392 species of benthic organisms have been identified.The composition was dominated by nearshore shallow water species,with tropical and subtropical species absolutely dominant.The total average of biomass was 38.0 g/m² and average density,116.0 ind./m².The communities of benthic organisms in the area can be classified into five communities namely,(1) Amphiura sp.-Acaudina molpadioides Community;(2) Protankyra asymmetrica-Arnphioplus pracstans-Murex trapa Community;(3) Modiolus meicalfei-Phyllophorus liuwutiensis-Armandia letocirris-Nephtys sinensis Community;(4) Branchiostoma belcheri-Solenr oseomaculatus-Marphysa sinensis- Onuphis eremita Community;(5) Iconomtra japonica-Barbatia decussata Community.
