This research is to investigate the growth relations in 103 nebka’s morphometric in Dashte Negar Bardsir in order to define the principles of management in nebka growing areas.In order to select the proper samples, the studied area was defined using google earth satellite images and several field works verified the extent of growing area of nebkas. Then morphometric and morphologic properties of nebkas were measured. The sampling method was based on one-dimensional sampling and the sampling unit was linear. The important morphometric elements that were measured were height of nebkas, base diameter of nebkas, nebka volume, plant canopy diameter and plant height. After measuring morphometric properties of nebkas, the relation between elements were defined using regression analysis. Since almost all of relations were in the form of allometric equations, the allometric relations of morphometric properties of nebkas were analysed and changes of nebkas form through the time were determined using this equations. Therefore allometric nature of nebkas in Bardsir is proven based on resulted equations. Identification of morphometric properties of nebkas and allometric analysis of them could be an index to determine the equilibrium phases of the nebkas and therefore could help to investigate the desertification process.

Keywords: Nebka, Morphometry, Allometry, Dashte Negar Bardsir, Iran.
