Antimicrobial peptides（AMPs）,which exists widely in living nature, are important part of innate immune system. AMPs not only have effective and brand spectrum antibacterial activities,but also have the activities against fungi,viruses,protozoa and cancer. Because of the different mechanism of antimicrobial action with antibiotic,the AMPs would not cause drug resistance and cross resistance. AMPs might be the new generation of antibacterial drugs,even have great market in agriculture,stock farming and aquaculture industry. Combined with the present research situation and development prospect of AMPs,this article summarized the source,categorization,structure,antibacterial mechanism and prospective application of AMPs.

To explore the spatial distribution pattern of negative air ion,the thesis used the Heilongjiang Province as the exploration area and chose 331 typical observation points to do the negative air ion observation. According to the datas we have,three interpolation methods were adopted（Ordinary Kriging method,inverse distance weighted method,radial basis function method） to do the spatial interpolation analysis of the negative air ion of 331 observation points in Heilongjiang Province. Correlation parameters were adopted,such as mean error,root mean square error,mean standard error,standard mean value,standard root mean square error,to compare the results of interpolation and study the effects of the results of negative air ion in this area that different methods brought to. The results showed that,the Moran’s I of negative air ion concentration in Heilongjiang Province was 0.36,indicated that the negative air ion had spatial autocorrelation in Heilongjiang Province. According to the comparision of four variograms models of Ordinary Kriging method（circulai model,spherical model,exponential model,Gaussian model）,it was found that the accuracy of exponential model was higher and this model was more suitable for the interpolation of negative air ion concentration. The regression analysis of 265 forecst sites and 66 validation sites showed that the focast figures and examine figures of three kinds of different interpolation methods had relevance. Significance level test R² results was Ordinary Kriging（0.840 33）,radial basis function method（0.803 96） and inverse distance weighting method （0.610 16） from high to low. According to synthetic comparision,it was found that optimal semivariogram for the exponential model of ordinary Kriging interpolation results of negative air ion concentration in Heilongjiang Province were the best,and it could focast the spatial distribution of negative air ion in Heilongjiang Province well.

The results show that the characteristics of NDVI can be well revealed by the wavelet analysis,the significant differences within the study area can be concluded by the t test. In the 7 different counties of the study area,the vegetation was in the slow recovery and the change of vegetation in the same vegetation type was changed by the years,but the vegetation growth cycle and growing period were different under the same type of vegetation and the climate. The vegetation growth cycle fluctuated around 230 days,the difference of vegetation growth cycle in different counties can reach 60 days. The vegetation growing period fluctuated around 110 days,the difference of vegetation growing period in different counties can reach 30 days. The reason was due to differences in temperature in particular months.

The thesis discussed the spatial distribution of Dalbergia odorifera seedling root system in simulated stony desertified soil （fully stony） by using refined whole root excavation method. The result showed that,in the fully stony substrate,the root-cap ratio of D. odorifera seedling increase. The distribution of root biomass in two different substrates were different in any direction except north（P<0.05）. In both substrates, when depth increased, root biomass of D. odorifera seedling increased first and then decreased. And the maximum biomass in two substrates appeared both from the depth of 10 cm to 15 cm. In stony soil,there were significant differences between root biomass from the depth of 10 cm to 15 cm and root biomass from the depth of 0 cm to 5 cm and from 15 cm to 20 cm（P<0.05）. However, in loam,root biomass had no significant difference in different depth. For D. odorifera with diameter less than 3 mm,there were significant difference between root biomass in stony soil and that in loam. For D. odorifera with diameter less than 0.5 mm, root biomass in stony soil was high than that in loam. Therefore, D. odorifera could change the distribution of root biomass and increase the proportion of thin-root to better adapted stony soil.

The results showed that the dust-retaining contents of per unit leaf area was relatively high for Euonymus japonicus and Pyracantha fortuneana,medium for Ligustrum×Vicaryi Hort and Ligustrum japonicum Thunb.,and relatively low for Pittosporum tobira and Photiniax fraseri. The absorbing ability of PM₁₀ for Euonymus japonicus,Pyracantha fortuneana and Ligustrum×vicaryi Hort all exceeded 0.20 g/m²,which was relatively strong. The absorbing ability of PM₁₀ for Euonymus japonicas was approximately 2.5 times than that of Photiniax fraseri. The adsorption capacity of PM₅ for Euonymus japonicus,Ligustrum japonicum Thunb. and Pyracantha fortuneana was relatively strong,whose dust-retaining contents respectively was 0.150,0.139 and 0.137 g/m². Photiniax fraseri was the lowest for 0.056 0 g/m². The adsorption capacity of PM_2.5 for Euonymus japonicus,Pittosporum tobira and Pyracantha fortuneana was relatively strong,the lowest for Photiniax fraseri. Further studies showed that Euonymus japonicus had better absorption for particulates out of its leaves with thick waxy structures,dense stomata as well as slight verrucous protuberances and grooves,While Photiniax fraseri had relatively weak absorption for particulates out of its smooth leaf surface.

Ivy glorybind（Calystegia hederacea） which reproduces mainly by rhizome can be used as an ideal model to study self/non-self discrimination. A greenhouse experiment including three treatments was set up：two connected ramets from the same genet,two dis-connected ramets from the same genet,and two ramets from different genets. The results showed that,compared with connected ramets,the above growth of the dis-connected ramets from the same genet had been inhibited. The rate of stem growth slowed down,branches from the stem base decreased,and biomass allocation to above stem and leaves reduced significantly,too. These results demonstrated that for ivy glorybind,neighboring ramets differentiated self from non-self through the connection of rhizome,which might enabled physiological integration and achieved a better fitness.

Chicory concrete from three different habitats were isolated by solvent extraction,and 29,36 and 26 components were determined by gas chromatography-mass spectrum（GC-MS）. The relative content of each peak was detected by the normalization method of peak area,palmitic acid,linoleic acid,ethyl linoleate,ethyl palmitate,ethyl linolenate and 2-acetylfuran are main components of this three concrete. The results showed that the volatile components of B was the most abundant,and the content distribution was uniform,concrete A and C has less content and mainly occupied by palmitic acid and linoleic acid.Flavouring test showed that these chicory concrete could improve cigarette flavour obviously and make cigarette flavour harmonious,plentiful,mellow and mild. The overall effect was B>A>C and 0.10% additive proportion was the best.

The contents of 12 mineral elements in the eggs among Tibetan chicken of Aba prefecture were determined by microwave digestion-inductively coupled plasma atomic emission spectrometry（ICP-OES）. The result shows that the contents of Ba,Ca,Cu,P,Mn in the egg shell among the three strains of Tibetan chicken of Aba prefecture were not significantly different （P>0.05）,the contents of Ca and P were high,accounting for more than 99% of the total content,while the content of Si,K,Ba,Fe slightly higher than other mineral elements;The contents of 12 mineral elements in the egg white were distant,but the differences between the three elements of P,Ba and Mn reached a significant level （P<0.05）;The average content of the mineral elements in egg yolk of the strain Ⅱ was higher than the others,except for Al,Cu,Pb and Si,and the difference among the three strains for the most mineral elements was reached a significant level （P<0.05）;The yolk is rich in elements such as Ca,Cu,Mn,P,Fe and Zn and the contents in egg yolk were twice higher than egg white.
