By field-work, interview, data getting and so on, the Nanjing bamboo gardening history is described, the Nanjing City area classical and modern landscape of bamboo is introduced, the outlook of Nanjing bamboo gardening and land-scaping is displayed for reference.

44 plots were set up in different slash pine plantations in 7 counties in Jiangxi Province,16 stand factors affecting the harm extent of the Hylobitelus xiaoi Zhang were surveyed in the study.

The results showed that the effect of all stand factors on the surface fuel loading was outstanding,but the close canopy mainly affected the 1-h time tag surface fuel loading,and stand average age mainly affected 10-h time tag surface fuel load.

The investigation shows that the stand factors(such as crown density,exposure and so on.

The advances in the study of physiological and ecological characters of tree seed germination were reviewed from the viewpoints of research history of seed physioecology,the relationship between seed configuration fabric and its germination,the relationship between seed germination and its environment.

A fast way to detect tree seed quality on its morphological character in X ray photograph,of distinguishing filled,emptied,worm eaten,and mechanical damage seeds,and creating permanent photo records for these different seeds and supplying scientific basis to seed production,trade,quality control,and management.

This article deals with the basic principles of dielectric separation of tree seeds.

Correlation between stand factors and arthropod community in Phyllostachys pubescens forest;

The results showed that the effects of all stand factors on the surface fuel loading were remarkable, but the stand average age and the close canopy mainly affected the 1 h time tag surface fuel loading, the stand average high mainly affected 10 h time tag surface fuel loadi.
