STUDIES ON THE SPATIAL PATTERNS OF THE POPULATIONS OF RHOMBOMYS OPIMUS AND MERIONES MERIDIANUS

The spatial patterns of the populations of Rhombomys opimus and Meriones meridianus in Tengenor area of Damaolianheqi Banner were studied during the period from October 1995 to October 1996. They were analyzed by means of the nearest individual, T distance sampling and negative binomial distirbution. The results were shown that Rhombomys opimus is in a state of collecting distribution around the all year but Meriones meridianus is of even distribution in summer. Collecting or even distribution is the states in winter but remarkably collecting distribution in summer between both populations shows negative relative in winter but positive one in summer.
