The sustainable development of coal mining cities in heilongjiang province has important effect on the economic stability and development of heilongjiang, Northeast China, and China at large. To further the sustainable development evaluation system of coal mining cities in heilongjiang province, based on the analytic hierarchy process （AHP） method combined with operational and scientific principles using Saaty＇s 1-9 scale method to construct the judgment matrix from five aspects, such as economic development and environmental quality, this paper establishes the comprehensive evaluation index sys- tem of sustainable development of coal mining cities in heilongjiang province, including comprehensive index of industrial economic benefits and the contribution rate of science and technology. In addition, using fuzzy comprehensive evaluation method, a comprehensive evaluation is made on the indices of the four major coal mining cities of heilongjiang. The result shows that the coal mining cities are not bet- ter than Datong of Shanxi province in many indices. The economic development and environment quality are the most important indices of the targeted layer influencing the sustainable development of coal min- ing cities of HeilonKiiang, and their index weights are 0.4358 and 0.2844, respectively. These two indices including comprehensive index of industrial economic benefit and the ratio of environmental protection investment to GDP are the key elements influencing the two aspects.

Concentrations of copper （Cu）, zinc （Zn） and manganese （Mn） were measured in four tissues of Tree Sparrow （Passer montanus） from three sites in heilongjiang province, China, during four seasons. Among the four measured tissues （primary feathers, liver, heart, and pectoral muscle）, the highest concentrations were found in feathers （Zn） or liver （Cu and Mn）, and the lowest concentrations were in muscle, except Cu. For Mn, mean concentrations of the birds from the three study sites were, in decreasing order： Didao mining area （DMA）〉 urban district of Jixi （UDJ）〉 Phoenix Mountain national nature reserve （PMR, the reference site）, but not for Zn and Cu. There were significant differences between metal concentrations at the three sites, but differences were not significant for Mn （in muscle and feathers） and Cu （in feathers）. For most elements, the mean concentrations were greatest in summer.

The forest resource of heilongjiang province has important position in china. On the basis of the six times of national forest inventory data （1973-1976, 1977-1981, 1985-1988, 1989-1993, 1994-1998, 1999-2003） surveyed by the Forestry Ministry of P. R. China from 1973 to 2003, the carbon storage of forests in heilongjiang province are estimated by using the method of linear relationship of each tree species between biomass and volume. The results show that the carbon storage of heilongjiang forests in the six periods （1973-1976, 1977-1981, 1985-1988, 1989-1993, 1994-1998, 1999-2003） are 7.164×10^8 t, 4.871×10^8 t, 5.094×10^8 t, 5.292×10^8 t, 5.594×10^8 t and 5.410×10^8 t, respectively., which showed a trend of decreasing in early time and then increasing. It indicated that heilongjiang forests play an important role as a sink of atmospheric carbon dioxide during past 30 years. Based on the data of forest fires from 1980 to 1999 and ground biomass estimation for some forest types in heilongjiang province, it is estimated that the amount of mean annual consumed biomass of forests is 391758.65t-522344.95t, accounting for 6.4%-8.4% of total national consummation from forest fires, and the amount of carbon emission is 176 291.39t-235 055.23t, about 8% of total national emission from forest fires. The emission of CO2, CO, CH4 and NMHC from forest fires in heilongjiang province are estimated at 581761.6-775682.25 t, 34892.275-46523.04 t, 14091.11-18788.15 t and 6500-9000 t, respectively, every year.

Background Human immunodeficiency virus （HIV-1） is divided into two types, HIV-1 （groups M, N and O） and HIV-2. heilongjiang province located in the northeast of China, and the feature of the subtype distribution and sequence characteristics of HIV-1 strains prevalent in heilongjiang province is still uncertain. The aim of this study was to investigate the subtype distribution and genetic characteristics of HIV-1 strains in one hospital in heilongjiang province. Methods HIV-1 env gene was amplified by nested-PCR from peripheral blood mononuclear cells （PBMCs） obtained from 19 HIV-1 seropositive individuals in heilongjiang province. The C2-V3 region was sequenced. Aligned the nucleotide sequence of 19 samples with CLUSTAL W （BioEdit） software, results were acquired and used for phylogenetic tree analysis after artificial adjustment. Reference sequence, downloaded from Los Alamos HIV Sequence Database, was used to identify the subtype of obtained sequence. Genetic distance between sequences was assessed using the software MEGA 3.1 Kimura 2-parameter, and the Phylogenetic tree was reestablished with Neighbor-Joining method. Results Phylogenetic tree analysis showed that 19 heilongjiang strains clustered closely to subtype B strain from Thailand and were far from other international subtype reference strains. Statistical test showed no significant discrepancy between the genetic distance of interclass and intra-class （P〉0.05）. The analysis of V3 loop amino sequence of 19 heilongjiang B strains revealed that V3 tip motif of 10 samples （52.63%） was GPGQ, and of 4 samples （21.53%） was GPGR. Conclusions The subtype of 19 HIV-1 seropositive individuals in heilongjiang province is B′, and it is introduced from He＇nan province. V3 tip motifs of the HIV-1 isolates are mainly GPGQ and GPGR.
