Endosymbiotic dinoflagellates in the genus Symbiodinium are among the most abundant and important group of photosynthetic protists found in coral reef *** order to further characterize this diversity and compare with other regions of the Pacific,samples from 44 species of scleractinian corals representing 20 genera and 9 families,were collected from tropical reefs in southern hainan Island,*** gradient gel electrophoresis fingerprinting of the ribosomal internal transcribed spacer 2 identified 11 genetically distinct Symbiodinium types that have been reported *** majority of reef-building coral species(88.6%)harbored only one subcladal type of symbiont,dominated by host-generalist C1 and C3,and was influenced little by the host’s apparent mode of symbiont *** species harbored more than one clade of Symbiodinium(clades C,D)*** geographically isolated from the rest of the Pacific,the symbiont diversity in southern hainan Island was relatively low and similar to both the Great Barrier Reef and Hawaii symbiont assemblages(dominated by clade C Symbiodinium).These results indicate that a specialist symbiont is not a prerequisite for existence in remote and isolated areas,but additional work in other geographic regions is necessary to test this idea.

[Objective]The aim was to study on effects of additives of traditional Chinese medicines on biochemical indices of blood of Wenchang chickens in hainan. [Method]About 180 female Wenchang chickens were divided into five groups at random with three repetitions for every group and twelve chickens for a repetition. Group 1 was control group and the chickens were fed with basic forages; the 2nd group was control group of antibiotics and the chickens were fed with basic forages and 600 mg /kg of aureomycin; group 3,4 and 5 contained 0. 1%,0. 2% and 0. 3% of the additives respectively,besides basic forages. Chickens at average weight were chosen six from every group on 35th and 56th days,respectively, to prepare serums for biochemical indices of bloods and analyze effects of additives on the indices. [Result]Serum cholinesterase activity and albu- min content were both improved by 0. 1%,0. 2% and 0. 3% of the additives （ P 〈0. 05） ; activity of alkaline phosphatase was enhanced,and serum cholesterol was lowered both by 0. 2% and 0. 3% of the additives （ P 〈0. 05） . [Conclusion]Additives of traditional Chinese medicines have an ac- tive effect on blood biochemical indices of Wenchang chickens.

作者： Wang Junguang, Zhao Zhizhong , Wang peng College of Geography and Tourism, hainan Normal University, Haikou, 571158, China

In this thesis, a series of samples collected during the survey in latosol in hainan island are analyzed to reveal the content distribution of heavy metals. And use of Geoaccumulation and N.L. Nemerow to evaluate the pollution of heavy metal in latosol. Through the geological cumulative index we can know, Cr, Zn, Pb elements in pollution-free to light pollution degree phase , Among them Cr element close to light pollution levels;Ni, Cd elements are in light pollution levels;Cu, As elements was in light pollution to heavy pollution stage .Using the latosol background value as evaluation standard, found Cd elements in the study area has reached the level of heavy pollution, Ni element does not cause soil pollution, Cr, Cu, Zn, As, Pb elements reached a level of light pollution in study area;7 kinds of Heavy Metal Pollution Index in the order of Cd＞Pb＞Zn＞Cu＞As＞Cr＞Ni. Using soil environmental quality standards, found most of the heavy metal element reach the national secondary standard, But individual elements in separate areas reach light pollution levels. In some areas the soil is not polluted, however ,some heavy metals reach the warning value , These areas should pay attention to.

An identification has been made of some shoshonitic intrusive rocks in central hainan Island recently. These rocks are K-rich (K2O=2.9%―5.1%, K2O/Na2O=0.95―2.12), distinctly enriched in LILE and LREE, strongly depleted in Nb, Ta, and moder- ately depleted in Sr and Ti, with (87Sr/86Sr)i = 0.70859―0.71425 and ε Nd(t) = (?2.77―?7.49). They were derived from an EMⅡ-type mantle source. The enrichment process is related to metasomatism of depleted mantle caused by a great amount of fluid-melt released from oceanic crust and terri- genous sediments at great depth (eclogite facies) during the subduction of the South China plate under the Indochina-South China Sea plate in the Carbon- iferous–Early Permian. A SHRIMP U-Pb zircon dating yields a crystallization age of 272±7 Ma for the sho- shonitic intrusions, which is coeval with the strongly peraluminous granites found in central hainan Island. These two kinds of rocks generally possess syn-intrusion ductile deformation structures. Thus they are considered to have been generated during the early stage (syn-thrust phase) of a post-collisional event. The primary magma of shoshonitic rocks was produced at a depth > 80 km by decompression- dehydration melting of previously enriched litho- spheric mantle wedge, phlogopite-bearing garnet peridotite, which was in turn caused by the break-off of a descendent slab and upwelling of a hot as- thenosphere. The rising of melts was accompaniedby crustal contamination and crystallization fractiona- tion (AFC). Combining with other related data, it is proposed that the southwards subduction and amal- gamation of the South China plate with the Indo- China-South China Sea plate took place at ca. 287- 278 Ma, which was a part of the convergence proc- ess of the Pangea supercontinent. The suture zone was probably located along the line of Song Ma-Beibu Gulf-north margin of the Yunkai Moun- tains-Wuyi Mountains.

According to hainan Island's biological characteristics, and existing structure of productivity of tropical crops and local climatic conditions, this paper carries on regional division of tropical crops by fuzzy mathematics. Based on calculation of basic parameters for tl1e formation of production, near-tem optimum models of tropical crops structure of each region was established by means of multi-objective programming, and a far-term grey programming model was set up through the above-mentioned near-term model and prediction of future parameters. Conclusion shows that the near-term programming may raise the profit by 5. 1-55.7 percent and far-tem programming by 54-90 percent, both gainingobvious economic benefits.
