The Homudu site was discovered closed to the northeastern part of the village Homudu in the Lo-chiang Commune of Yu-yao zhejiang sheng.The excavations were conducted in 1973-1974 and 1977-1978.Four layers of cultural deposits are super- posed one upon the other.The first and topmost layer corresponds to the middle layer at Sun-ts'e in Ch'ing-p'u Country,while the second layer represents the Ma-jia-bin Cul- ture of Chia-hsing Country.The third and fourth layers belong to a hitherto unknown culture,which has been provisionally named as the Homudu Culture. A palynological and paleobotanical study is made for showing the paleovegetation and palcoclimate of that time. 1.The first sporo-pollen assemblage,obtaind from the fourth and lower part of third layers is marked by predominence of Gramineae pollen(11-71%).The majority of Gra- mineae pollen is of large size.Exine is thin and more psilate.Annulus of the single pore is about 2.5-3.7μm in wide.This kind of pollen very much resembles that of the recent rice(Oryza sativa). Besides that,the herbaceous pollen of Artemisia,Caulophyllum,Actinostemma,Poly- gonum,Rubia and some elements of Cyperaceae,Chenopodiaceae,Umbelliferae are noted. Pollen of trees and shrubs belong to Quercus,Castanopsis,Liquidambar,Mallotus,etc. Fern spores are of Lygodium.Ophioderma,Lemmaphyllum,Microsorium and Pyrrosia.A lot of plant remains(leaves and seeds)have been observed in the fourth layer:Chloran- thus fortunei,Magnolia coco?,Phoebe sheareri,Lindera glauca,Camptotheca acuminata Prunus davidiana,Choerospondias axillaris,Trapa bispinosa,Quercus myrsinaefolia,Cas- tanopsis tibetana,etc. Sporo-pollen assemblage and plant remains reflect a subtropical everygreen and de- ciduous broad-leaved mixed forests flourished on mountain slopes and some rice fields scattered in the plains around the site.The climate of that time was warm and humid and rather warmer than that of the present. Radiocarbon tests of an acorn and a wood fragment unearthed from the fourth layer reveal that they date from about seven thousand years ago,corresponding to the Atlan- tic period of Europe.2.The second sporo-pollen assemblage,obtained from the middle and the upper parts of third layer is prcdominent by pollen of trees,such as Quercus spp., Liquidambar formosana and others.In herbs,the pollen of Gramineae,Cyperaceae and water plants deereased,but those of Artemisia and Chenopodiaceae increased.The climate than was warm but somewhat drier than that of previous period.3.The sporo-pollen as- semblages from the second and the first layers were mainly composed of temperate ele- ments,such as Quercus,Ulmus,Salix,Where the subtropical elements Liquidambar and Altingia decreased or completely disappeared.These indicate that the climate become cooler than that of the previous periods. Radiocarbon tests of a wood fragment obtained from the second layer reveal that its date was from 5600 years ago,then the age of the second layer would correspond to the Subboreal period of Europe. A lot of rice pollen grains,along with a large amount of the remains of rice busks were obtained from the fourth layer in the site,which indicats that the rice plants were cultivated in China at least seven thousand years ago. 本文根据古植物资料,分析并推断了“河姆渡”先人生活时期的古植被、古气候。 This article introduces remarkable achieve-ments made in the field of energy saving in thecity of Yantai as a result of hard work.The coalconsumption for clinker per ton in the buildingmaterials industry of this city has been reducedat the speed of 2.65% every successive year byraising understanding, strenthening leadership,respecting science, relying on techniques, con-solidating management, laying solid foundation,setting up good models whose experience promotesthe work in the entire area.

This article introduces remarkable achieve-ments made in the field of energy saving in thecity of Yantai as a result of hard work.The coalconsumption for clinker per ton in the buildingmaterials industry of this city has been reducedat the speed of 2.65% every successive year byraising understanding, strenthening leadership,respecting science, relying on techniques, con-solidating management, laying solid foundation,setting up good models whose experience promotesthe work in the entire area. The total industrialproduction output value and profits accomplishedin the building materials industry in Yantai in theperiod of January to October of 1984 was 12.84%and 13.95% respectively over the previous period,while the comprehensive energy consumption perevery ten thousand Yuan was reduced by 6.6%.The average standard coal consumption per tonclinker in sixteen cement plants above county'slevel in Yantai is 116.98 kg, while the averagecomprehensive power consumption per ton cementis 79 K.W.H., considerably lower than the provin-cial and state level. Therefore, Yantai has beenlisted by the State Administration of Building Ma-terials Industry as one of the lowest energy con-sumption units for local cement. Some cementplants has got rewards honourably. 千方百计节能增产,是关系到振兴建材工业的重大战略问题。我们务必提高认识,采取有效措施,使建材行业由耗能大户逐步变为节能大户。本期摘编了国家建材局局长林汉雄同志在第二次全国建材工业节能工作会议上的讲话,选编了若干节能先进单位的典型经验,供大家学习参考。 Every year during late spring and summer, a cold water area exists on the sea surface near the east side of Subei (northern Jiangsu) shoal patch. The main cause of the cold water area is the monthly southward migration and the climbing up against the slope of deep cold water frown the western part of the south Huanghai Sea (Yellow Sea). The existence of the deep ditches on the north side of the under water delta off Subei decides the position fixation of this cold water. Besides, another cold water area is... Every year during late spring and summer, a cold water area exists on the sea surface near the east side of Subei (northern Jiangsu) shoal patch. The main cause of the cold water area is the monthly southward migration and the climbing up against the slope of deep cold water frown the western part of the south Huanghai Sea (Yellow Sea). The existence of the deep ditches on the north side of the under water delta off Subei decides the position fixation of this cold water. Besides, another cold water area is commonly observed on the surface in the region 32°N and 124°—124.5°E during late spring and summer. This water mainly comes from the deep layer of northwest area; its upwelling is related with northward "impulsefashions" extension of Taiwan Warm Current in the previous period, and its position fixation is probably related with under-water reef chain there. 每年春夏之际,在紧靠苏北浅滩东侧海面有一冷水域存在。黄海西南部深层冷水的逐月南移并逆坡爬升是这一冷域的主要成因;而苏北外海水下三角洲北侧海底深沟的存在决定了这一冷域的位置。另外,春夏期间在32°N,124°—124°30′E海面,也经常观测到另一冷域的存在。据分析,此冷水主要来自黄海西北部的深层,而冷水的上涌则与前期台湾暖流的“脉冲型”北伸有关。
