The Study of Ecological Changes and Seriate Structure of Markazi Province Forest (Case Study: Shazand Province,Oak jungles)

The first step for permanent management of jungles is to have some information about the principle of jungles up growth and their natural structure (in accordance with environmental factors) without being aware of up growth principles and degree of sensitivity ecological balance will be in a serious danger so the purpose of this research is to indicate the status of a natural structure cumulus of Oak stability and to estimate the upgrowth stages (seriate trend) that will be so helpful to indicate the degree, the number and the changes in jungles dynamism .moreover to indicate the proper methods of management. For this purpose an area which is the only one included Oak jungle was studied at Shazand province (in markazi province). To study the vegetal cover with respect to some factors such as very great genetic and supportive value and the necessity of high-processor in our studying for indicating the trend of ecological changes and seriate trend, we used complete statistical method and some qualities such as tree figuration ,format ,height and the number of buds ,the average of canopy diameter and tree situation ,was studied. The study of variance diagram of diameter levels showed that the area has a noneven-aged decreasing structure and it consists of double hump distribution. The study of number of variance diagram in altitudinal ranks distinct that this curve is in a near normal and toward right with a little slope status. But the study of ecological change trends and seriate structure of Oak stability in accordance to horizontal and perpendicular structure of area, dried trees and reproduction also the attention to the development cycle of natural area showed this area is in an optimal stage and is going to an ageing one. For this reasons in the jungle area with the same up growth situation, the correct and suitable methods should be chosen ,before getting this level of up growth to do this we should indicate and clarify the phases observed in an up growth cycle, through the of cartography. Then we should analyze every bole in every specific phase to indicate the length of every phase to finally be able to indicate the time limit, area and the amount of intensity of our interference in every part of jungle also we should pay attention to the kind of the management operation for achieving the best structure.
