The research on Urban ecological environment planning in arid area was developed,taking the Ba Yan Hot of eastern edge of Teng Ge Li desert as an example.

On base of analysis on the characteristics of urban land classification and evaluation in Bayehot, the evaluating characteristics of base land value in Bayehot were summerized, the average of classification base land value,the average of grade base land value ,the similar chain indexes of land value and similar rate indexes of land value at all levels were calculated.

In the Bayanhaote Basin,there is a linear correlation between the depths of the enclosure samples in different ages and the homogenization temperatures of enclosure, especially those in middle and later periods, and there can be divided in vertical direction into four stages which are immature stage,low mature stage, mature stage and high mature stage.

According to exploring result in the Bayanhaote Basin,the petroleum system is analyzed, and two petroleum systems are distinguished,those are Hercynian Indosinian de.

Carboniferous Reservoir Features and Diagenesis,Bayanhot Basin;

The structural evolution of Bayanhot Basin underwent a structural transform from compressional deformation to extensional deformation.

Based on age study of apatite fission track of Carbonif-erous in Bayanhaote basin,it is believed that the annealing age was after Jurassic and Jurassic had not experienced tem-peratures over120℃ever since then while Carboniferous largely reached the highest annealing temperature of apatite at the end of Cretaceous.

The surface of Bayanhaote basin is covered largely by desert and gobi.
