The soil microbial distribution of bacteria，fungi，and actinomycetes in five different Larix gmelinii forests［（A） Ledum palustre-Larix gmelinii virgin forest，（B） herbage-Larix gmelinii virgin forest，（C） Betula fruticosa-Larix gmelinii virgin forest，（D） Larix gmelinii forest burned-over areas，and （E） clearcut Larix gmelinii forest］ in 0 － 10，10 － 20，20 － 30 cm soil layers was studied in the National Forestry Ecosystems Station of Inner Mongolias Great Xingan Mountains using the dilution-plate method. Results showed that in the different forest types，soil microbes varied in quantity，category，and vertical distribution（P＜0.05）. Also，bacteria were dominant accounting for 80.2% － 96.8% of the microorganisms. Numbers of all microorganisms in the Larix gmelinii forests were in the order：A＞B＞C＞D＞E；whereas bacteria were A＞B＞C＞D＞E，fungi were E＞C＞A＞B＞D，and actinomycetes were A＞B＞D＞E＞ C. In virgin forests actinomycetes in the 10 － 20 cm layer were greater than the 0 － 10 cm layer；but vertical distribution of bacteria and fungi decreased（P＜0.05） with the increasing vertical depth.［Ch，4 fig. 1 tab. 15 ref.］

To study the characteristic of the caloric value and ash content of dominant tree species in an evergreen broadleaf forest in Ailaoshan National Nature Reserve，Yunnan Province，the caloric value and ash content of six dominant tree species：Lithocarpus xylocarpus，Schima noronhae，Machilus bombycina，Ilex gintungensis，Camellia forrestii，and Castanopsis rufescens，were analyzed respectively on leaves，branches，trunks，trunk barks，and roots by sampling in the field and analyzing in the laboratory. Results showed ranges of gross caloric value of six dominant species were（in kJg-1） 19.0 － 23.41 for leaves，19.22 － 21.47 for branches，18.22 － 21.24 for trunk bark，19.32 － 21.27 for trunks，and 18.89 － 20.90 for roots. Tree gross caloric value ranked：L. xylocarpus ＞ S. noronhae ＞ M. bombycina ＞ I. gintungensis ＞ C. forrestii ＞ C. rufescens，whereas the rank of ash-free caloric values was：L. xylocarpus ＞ M. bombycina ＞ S. noronhae ＞ I. gintungensis ＞ C. rufescens ＞ C. forrestii. Both gross caloric values and ash-free caloric values were not consistent with the sequence of the importance value of these tree species. The caloric value were correlated remarkably with ash content （P＜0.01）.［Ch，4 tab. 22 ref.］

To provide a scientific basis for reasonable exploitation of bamboo resources，temporal and spatial variation patterns of the microfibril angle（MFA） in Phyllostachys pubescens（moso bamboo） were studied. Buried rhizomes （R） and seedlings （S） aged 30，54，and 78 months were measured and analyzed by X-ray diffraction estimation. Results showed that when the distance ranged from bark to pith for all bamboo，MFA radial variation of secondary cell walls for the three ages decreased or had no pattern. The maximum MFA（R） was 12.05 and MFA（S） was 10.97 with the minimum of 7.67 ［MFA （R）］ and 8.24 ［MFA （S）］ for a difference of less than 5. There was a significant difference between age and MFA（P＜0.05） but no regular pattern. No pattern for longitudinal variations of MFA with bamboo height were found with bamboo rhizomes having a base of 9.64，a middle of 9.25，and a top of 9.34，significantly（P＜0.05） more than bamboo seedlings of 9.73 for the base，9.82 for the middle，and 9.58 for the top. ［Ch，4 fig. 3 tab. 22 ref.］

A comparison of 1.5 m above ground aero-anion and positive air ion concentration for six plant communities，Pinus massoniana，Sapindus mukorossi，Magnolia grandiflora，Phyllostachys praecox，Cunninghamia lanceolata，Lagerstroemia indica，and turf grass，was conducted using a correlation analysis with relative humidity，temperature，solar radiation intensity，and ultraviolet radiation intensity. Results showed that compared to a corresponding open space，the aero-anion effect was better in each plant community，and their individual aero-anion concentration was in the order of P. massoniana＞S. mukorossi and M. grandiflora＞P. praecox＞C. lanceolata＞L. indica＞turf grass. According to the diurnal variation curve between 7 : 00 and 19 : 00，the aero-anion concentration tended to double peak from 9 : 00 - 10 : 00 and 15 : 00 - 16 : 00. A correlation analysis showed a significant（P＜0.01） positive correlation （r = 0.702） between aero-anion concentration and relative humidity，a significant（P＜0.05） negative correlation（r = － 0.637） between aero-anion concentration and temperature，a negative correlation（r = － 0.191） between aero-anion concentration and solar radiation intensity，and a significant（P＜0.05） positive correlation（r = 0.580） between aero-anion concentration and ultraviolet radiation intensity（UVB）.［Ch，2 fig. 3 tab. 15 ref.］

To form a basis for constructing a root-water-uptake model of triploid Populus tomentosa，spatial distribution characteristics of fine roots were studied through wide （6 m） and narrow （2 m） row spacing planting schemes，and soil coring method using correlation，regression and variance analyses. Results showed that vertically，in both wide and narrow spaced rows，the fine roots were mainly concentrated within the 0 － 20 cm soil layer where their amount were 0.080 cmcm-3 and 0.074 cmcm-3 accounting for 44.1% and 48.7% of the total，respectively. For a radial distance of 100 cm from the stem，the fine root length density of 0 － 20，20 － 40，40 － 60 and 60 － 80 cm soil layer in a wide row increased by 35.45%，36.76%，71.67% and 72.27% as compared with that of the corresponding soil layer in a narrow row. Horizontally，in the wide row fine root length density from 20 － 200 cm showed an exponentially declining distribution. The fine roots were mainly concentrated within the 20 － 80 cm soil zone，and within the 0 － 200 cm range these roots were 0.250 cmcm-3 occupying 49.20% of the area. The fine roots in the narrow-spaced row were distributed irregularly with no significant differences among the fine root length densities for different radial distances. In addition，a one-dimensional （R2 = 0.228） root length density function was fitted to narrow spaced rows，while the two-dimensional （R = 0.538） was fitted to the wide row.［Ch，5 fig. 2 tab. 12 ref.］

Bambusa oldhamii f. variegata is a form of Bambusa oldhamii，having good ornamental and economic value. This aim is to establish a tissue culture system for its commercial propagation. Multiplication of B. oldhamii f. variegata using different plant growth regulators and concentrations was studied with the lateral buds as the explant and three shoots per cluster. The results showed that 0.1 mgL-1 thidiazuron（TDZ） was best with the proliferation rate up to 3.60 when TDZ（0.000 1，0.001 0，0.010 0，0.100 0， 1.000 0 mgL-1），6-benzylaminopurine（BA）（1，3，5，10 mgL-1）、2-isopentenyladenine （2ip） （1，3， 5，10 mgL-1） and kinetin （KT）（1，3，5，10 mgL-1） were added respectively to determine suitable concentration for tissue culture，but the highest proliferation rate 4.63 was obtained with 3.00 mgL-1 BA + 0.01 mgL-1 TDZ when the combination of BA（0.001，0.010，0.100，1.000，3.000 mgL-1），TDZ（0.000 1， 0.001 0，0.010 0，0.100 0 mgL-1），and also good growing. Three shoots per cluster was treated only with 50.00 mgL-1 indole-3-butyric acid（IBA） for 1 day，then the explants were transferred to MS（Murashige and Skoog） basic medium，After 30 days the rooting rate was up to 55 percent，and developed well. The survival rate of transplanted potted plants was above 85 percent.［Ch，1 fig. 4 tab. 13 ref.］

Because of its characteristics such as high pH value，high-salt content，poor structure and low fertility，saline and alkali soil has harmful effect on both plant growth and eco-environment. Therefore，it is important to improve and utilize the saline and alkali soil. According to the relevant research in China and abroad，this paper reviewed the main causes of the saline and alkali soil，including soil parent material，texture，landform，neotectonics，hydrological condition，human activities，and analyzed biotechnologies such as germplasm screening，distant hybridization and genetic engineering as well as non-biological technologies including tillage fertilization，covering technique，hydraulic measures，chemical measures and electro-magnetic methods. And suggestions are raised，namely further improving regional salt forecast system and giving play to plant-microorganism combined bioremediation for the soil.［Ch，52 ref.］
