Abstract:
The poplars (Salicaceae Mirbel subfam.Populoideae Kimura) contain two genera (i.e.Balsamiflua et Populus) with more than 50 natural species (as well as a great number of natural hybrids et artificial hybrids),and distribute naturally in Tropical Africa et in the Northern Hemisphere roughly from 19° to 70° north latitude;Balsamiflua of about 8 species disperses disjunctively in Equatorial Africa,Tethys regions et southeastern North America;Populus of more than 40 species widely ranges in Africa,Asia,Europe et North America approximately between the Tropic of Cancer and the Arctic Circle.It is probable that the salicaceous late ancestor originated from the West Gondwana land during the Early Cretaceous,and gradually developed into extant poplars (i.e. Balsamiflua et Populus) et extant willows (i.e.Pleiarina,Chosenia et Salix) through two intermediate links (i.e.Archaic poplar group et Archaic willow group) respectively.The Archaic poplar group (i.e. the direct ancestor of the poplars) probably emerged from the West Gondwana land during the Middle Cretaceous;subsequently,it seattered over the areas concerned (especially the north Laurasia),and differentiated et evolved further in the course of its migrating.The genus Balsamiflua possibly occurred in Africa land during the Middle et Late Cretaceous,and dispersed progressively into the Laurasia;then,the unitary Balsamiflua flora was divided into several distant parts developing alone owing to the breakup of the Laurasia et the formation of the Sahara.The genus Populus might rose and differentiated in eastern Tethys regions during the Middle et Late Tertiary;afterwardz,it widely spread in Eurasia land and gradually migrated to North America land via Bering regions.Besides,a conspectus of all the genera and species of the plants concerned and a key to the subfamilies et genera of Willow Family are provided in the present paper.

Abstract:
In this paper,studies were made of the soil water-holding capacity of 7 typical ecosystems,which were grass land (dominated by Deyeuxia scabrescens),shrub (dominated by Salix paraqplesia),broadleaf forest (dominated by Betula platyphylla),mixed forest (dominated by Betula spp.and Abies faxoniana),fir forest (dominated by Abies faxoniana),spruce forest (dominated by Picea purpurea) and cypress forest (dominated by Sabina saltuaria) in Wanglang National Nature Reserve (WNNR)in the subalpine of western Sichuan by field survey and ring shear testing,and the assessment were conducted on the regional soil water-holding capacity in Wanglang National Nature Reserve (WNNR).The results indicated that in the studied 7 ecosystems,the soil bulk density increased with the increasing of the depth while the soil water-holding capacity decreased with the increasing of the depth significantly.Ecosystems largely affected the soil bulk density and soil water-holding capacity,and the soil of mixed forest had the smallest bulk density and the largest water-holding capacity.The soil of WNNR could hold 90 870 361 t in all of the studied 7 ecosystems,which were contributed by grass land and mixed forest.Therefore,the contribution to regional soil water-holding depended on the size of a given ecosystem and its water-holding capacity.It was also indicated that ecosystem management for increasing the water-holding capacity should be strengthened to establish the mixed forest,and much attention should be paid to the ecosystem structure and removing human disturbance.

Abstract:
Taxus media(TM),a plant of dioecism,had very high medicinal and ornamental value for the beautiful figure and the high contents of paclitaxel in all its parts.The research was conducted on analyzing the morphological characteristics of branches and leaves among one male and two female plants of TM in Hongya,Sichuan province.The results showed that:①The morphological characteristics of branches could be used as the important appraisal standard to distinguish male and female plants.Branchlets of both two female plants were nearly verticillate.The internodal length of the No.1 was about 25 cm and the number of branches was 4~5 per node.The internodal length of No.2 was only 7 cm~8 cm and the number of branches was 7~8 per node.Branches of the male are distributed on the same plane.The internodal length was only 3 cm to 5 cm and the number of branches was 2 or 3 per node.②As compared with the two female plants,the male leaf of TM was much narrower,while leaf length,leaf area and leaf index of the male plants were larger.③The fresh weight,dry weight and specific weight per leaf of the No.2 female plant were lower than those of the No.1 female plant and the No.1 male.In conclusion,there were three different types of male and female TM in Hongya,Sichuan province,after nearly 20 years of introduction and domestication,while significant differences of morphological characteristics were found.The morphological characteristics could be used to identify the male and female plants of TM,which could have great practical value in production practice.

Abstract:
By adopting the nest sampling method,studies were made of sampling techniques for clonal population of Bashania faberi in Wuyipeng Ecological Observation Station of the Giant Pandas,Wolong National Nature Reserve.The determinnation indexes included population density,plant coverages of all layers below bamboo forests,bamboo stem diameter and length of each age-class within 1.00 m2 quadrat.In the meanwhile,sampling area increased from 0.01 m2 to 25.00 m2.Statistical analysis of 3 indexes in different sampling area showed that the population density had a tendency to decrease when sampling-area enlarged,and with the increase of the survey-time,the change range of the plant coverage of all layers reduced.After comprehensive consideration it was thought that 1.00 m2 was the best sampling area for the clonal population of Bashania faberi.Finally,the growth index(stem diameter and length) between "total quadrat" plants and 10 strains of random selected perennial bamboo was compared.The quantitative analysis results showed that there was no significant difference (P>0.05) between these two sampling techniques and thus verified the usefulness of bamboo population survey methods during the past route monitoring.

From May 2014 to April 2015,the survey of bird and mammal diversity was conducted by using the infrared trigger automatic camera in Jiuzhaigou National Nature Reserve.Set infrared-cameras were set in 30 location,Altogether 2 832 photos were taken in 3 153 working days.There were 525 independent photographs (IP) which could be identified,among them 161 were bird IP,356 were mammal IP and 8 were disturbed IP from human activities and livestock grazing.We have identified 13 species of birds (belonging to 6 families and 2 orders) and 16 species of mammals (belonging to 9 families and 3 orders).of which 11 species were listed in Chinese National Key Protected Wild Animal Species.For mammals,Elaphodus cephalophus,Capricornis milneedwardii,Naemorhedus griseus,Tamiops swinhoei and Budorcas taxicolor topped the ratings,and yellow-bellied weasel(Mustela kathiah) was a newly recorded species found in this survey.For birds,Turdus rubrocanus,Crossoptilon auritum,Trochalopteron elliotii,Parus monticolus and Ithaginis cruentus topped the ratings.In the mean while,it was found that the species of ungulates such as Capricornis milneedwardii and Naemorhedus griseus were suffering from sarcoptidosis.It's necessary for the Reserve to take measures to monitor and control the disease.Besides,the discussion was made on some frequent problems in the application of infrared camera technology to the monitoring of the natural reserve.

Abstract:
In this study,investigations and analysis were made of natural enemies and pests in nonpolluted tea gardens,general tea gardens and organic tea gardens in Mingshan,in order to contrast their ecological environments between 3 kinds of tea gardens.The results showed that there were found pests of 8 orders,45 families,and 75 species,and natural enemies of 11 orders,36 families,and 71 species.The main pests were mites,scale insects,leafhoppers,aleyrodids,Scirtotuthrips dorsalis,and Toxoptera aurantii etc.The main natural enemies were spiders,ladybugs,hoverflies and parasitoid wasps.The analysis of the dynamic curves of main pests and natural enemies showed that the organic tea garden was most consistent with the natural law evolution,the general tea garden was next,and the general tea garden was the worst.
