    随着中国房地产行业的告诉发展并日趋成熟,房地产业已经成为国民经济的增长点,房地产评估作为市场提供专业估价服务的中介也得到迅猛发展。 房地产估价即房地产价格评估,就是对房地产进行估价,由持有《房地产估价人员岗位合格证书》或《房地产估价师注册证》的专业人员,根据估价目的,遵循估价原则,按照估价程序,运用估价方法,在综合分析,影像房地产价格因素的基础上,结合估价经验及对影像房地产价格因素的分析,对房地产的特定权益,在特定时间最可能实现的合理价格所作出的估计、推测与判断。它实质上不使估价人员的定价,而是模拟市场价格形成过程,将房地产价格显现出来,它具有专业性、技术性、复杂性。 房地产评估管理系统以...With the development of Chinese real enterprise,it has become a new growth point of national economy, and the evaluation delegation service have also been under the rapid develoment.

    为了解广州南沙十四涌潮间带大型底栖动物的群落结构,于2007和2008年在十四涌潮间带选择光滩、海桑(SOnnErATIA)和茳芏(CyPEruS MAlACCEnSIS)3种生境进行大型底栖动物调查。对4个季度定量取样获得的大型底栖动物群落结构和差异进行比较分析,结果表明:从种数、平均生物量和丰度指数上看,茳芏生境最多,光滩第二,海桑生境最少;从大型底栖动物平均密度、种类多样性指数和均匀性指数上看,光滩最高,茳芏第二,海桑生境最低。AnOVA分析表明,3种生境间大型底栖动物的物种数、密度均呈显著差异,但生物量无显著差异。非度量多维标序(MdS)和聚类分析表明,冬季光滩和茳芏生境的大型底栖动物群落比较相似;3种生境的春季和夏季大型底栖动物群落比较相似。同时对3种生境间群落组成和数量差异的原因进行了探讨。In order to understand the community structure of macrofauna in the 14th Yong intertidal zone of Nansha,Guangzhou,an investigation was made at three different habitats,i.e.,bare tidal flat,Sonneratia habitat,and Cyperus malaccensis habitat from 2007 to 2008,with the seasonal variations of the macrofaunal community structure at the habitats compared and analyzed.The species number,average biomass,and species richness index (d) in four seasons were all the highest at C.malaccensis habitat,the second at bare tidal flat,and the lowest at Sonneratia habitat; while the average density,species diversity index (H′),and evenness index (J) were the highest at bare tidal flat,the second at C.malaccensis habitat,and the lowest at Sonneratia habitat.ANOVA analysis showed that there was a significant difference in the species number and density among the habitats,but no significant difference in the biomass.MDS and cluster analysis showed that in spring and summer,the macrofaunal community at the three habitats was similar,but in winter,only the macrofaunal community at bare tidal flat and C.malaccensis habitat was similar.The causes for the differences in species composition and quantity among the three habitats were discussed.国家自然科学基金重点资助项目(30930017

    为了比较漳江口4种植物生境之间多毛类动物群落的差异性,2010年对漳江口潮间带秋茄、桐花树、白骨壤和互花米草4种植物生境的多毛类动物进行4个季度的定量取样.共获得15种多毛类动物,4个季度在4种植物生境中均出现三角洲双须虫、溪沙蚕、拟突齿沙蚕、凿贝才女虫、小头虫和加州中蚓虫.多毛类动物栖息密度、生物量、丰度指数、均匀度指数和多样性指数的季节变化不明显;但4种植物生境之间多毛类动物栖息密度、生物量、丰度指数、均匀度指数和多样性指数有显著差异,且互花米草生境与3种红树林生境之间多毛类动物优势种不同.PEArSOn相关分析表明,漳江口红树林和盐沼湿地除了多毛类物种数与泥温显著相关外,多毛类动物栖息密度、生物量、丰度指数、均匀度指数和多样性指数均与泥温、盐度、总有机碳、总氮无显著相关关系,其原因是漳江口4种植物生境多毛类动物常见种小头虫、加州中蚓虫和溪沙蚕均是广温、广盐及耐高有机质含量的种类.In order to understand the community structure of polychaete in different botanic habitats in Zhangjiang River Estuary,an investigation was conducted in the habitats of Kandelia candel,Aegiceras corniculatum,Spartina alterniflora,and Avicennia marina in four seasons,2010.A total of 15 polychaete species were recorded,and 6 species including Eteone delta,Namalycastis abiuma,Paraleonnates uschakovi,Polydora ciliata,Capitella capitata,and Mediomastus californiensis were found in the four habitats and four seasons.The density,biomass,richness index,evenness index,and diversity index of the polychaete had no significant differences among seasons but significant differences among habitats,and the dominant species of polychaete in S.alterniflora habitat differed from that in the other three mangrove habitats.Pearson correlation analysis showed that in the mangrove and salt marsh,there were no significant correlations between the polychaete parameters(density,biomass,richness index,evenness index,and diversity index) and the environmental factors(sediment temperature,salinity,total organic carbon,and total nitrogen),except that the species number of polychaete had significant correlation with sediment temperature due to the common species of polychaete such as Capitella capitata,Mediomastus californiensis,and Namalycastis abiuma in the mangrove and salt marsh in Zhangjiang River Estuary being of eurytherm and eurysalinity,and resistant to high organic matter content.国家自然科学基金重点项目(30930017)资

    为了比较湛江高桥潮间带不同植物生境的大型底栖动物次级生产力,根据2010年4个季度湛江高桥潮间带生境的大型底栖动物数据,运用brEy经验公式计算不同植物生境的大型底栖动物次级生产力.结果表明:湛江高桥红树林和盐沼湿地不同生境大型底栖动物平均次级生产力为11.77gAfdM·M-2·A-1.其中,无瓣海桑生境次级生产力最高,为18.16gAfdM·M-2·A-1,其次是桐花树、盐地鼠尾粟和木榄生境,分别为17.67、8.34和2.92gAfdM·M-2·A-1.在4种生境中,木榄生境的年生产力/年均生物量(P/b)最高,为2.38,其次是无瓣海桑、盐地鼠尾粟和桐花树生境,分别为1.23、0.99和0.48.湛江高桥潮间带不同植物生境大型底栖动物次级生产力和P/b值的差异主要与总有机碳含量、食物类型和动物个体大小有关.In order to understand the secondary productivity of macrobenthos in different botanic habitats in intertidal zone in Gaoqiao of Zhanjiang,the Brey's empirical formula was applied to calculate the secondary productivity based on the investigations in the habitats of Sonneratia apetala,Aegiceras corniculatum,Sporobolus virginicus,and Bruguiera conjugate in four seasons,2010.The secondary productivity of the macrobenthos in the habitats in four seasons was averagely 11.77 g AFDM·m-2·a-1,being the highest in S.apetala habitat(18.16 g AFDM·m-2·a-1),followed by in A.corniculatum habitat(17.67 g AFDM·m-2·a-1),S.virginicus habitat(8.34 g AFDM·m-2·a-1),and B.conjugate habitat(2.92 g AFDM·m-2·a-1).The P/B ratio of the macrobenthos was the highest in B.conjugate habitat(2.38),followed by in S.virginicus,S.virginicus,and A.corniculatum habitats,with the values of 1.23,0.99,and 0.48,respectively.The differences in the secondary productivity and P/B ratio of the macrobenthos among the four botanic habitats were mainly related to the sediment total organic carbon,food type,and macrobenthos individual size.国家自然科学基金重点项目(30930017)资
