[ Objective ] The paper was to study the relationship between community structure and diversity of ladybugs in Baihualing of Gaoligong Mountain with altitude changes. [ Method] The community and diversity of ladybugs in vertical level in Baihualing of Gaoligong Mountain was investigated. [ Result] The species diversity of ladybugs was the greatest at the medium altitude level （ 1 600 - 1 900 m）, which gradually decreased in low and high altitude. The greater the altitude span was, the lower similarity between communities of ladybug was, and vice versa high; the similarity of ladybug communities in protected areas was relatively higher, while it was relatively lower in fanning areas. The altitude level of 1 600 - 1 900 m with the highest community diversity of ladybugs shared low similarity with the community diversity of ladybugs in other altitude levels. [ Conclusion] The study provided theoretical basis for the further study on ladybugs in Baihualing of Gaoligang Mountain.

With the support of the UNEP/GEF Siberian Crane Wetland Project,a five-year field survey of breeding waterbirds was conducted in four nature reserves - Zhalong,Keerqin,Xianghai and Momoge National Nature Reserves in the Songnen Plain for the period from May 2004 to August *** purpose of the survey was to improve our understanding of the distribution and populations of breeding waterbirds in this *** Red-crowned Crane (Grus japonensis) was the most important target *** survey results confirm that the Zhalong wetland is the largest breeding ground for the Red-crowned cranes in the Songnen *** 90％ of the breeding birds were found in Zhalong,with numbers fluctuating from 112 to 275 over the *** (Phragmites australis) is the most important plant species associated with breeding locations of this bird *** supply to the wetland can relieve pressure from deterioration of wetland habitats for the breeding of Red-crowned ***,a sound scientific basis for the water supply mechanism is the key to better management of their habitat and a prerequisite for ensuring the breeding success of the Red-crowned Crane.
