The main reason of landscape patten change owes to the external disturbance. In this article, retrospective sequential airphotoanalysis and statistical analysis of information on landscape development were used and two remarkable changes of landscape pattern in west Shenyang were identified: (a) one landscape element becomes a new matrix in place of the former one; (b) landscape proportions among several constiting elements changed significantly. This paper studied spatial pattern of the landscape using following quanta indices: (1) number and size of patches, (2) transition matrix of patches, (3) priority index of each kind of patch and (4) diversity and evenness indices of landscape.The results show that the landscape of west Shenyang has been more and more disturbed by human activities, so it becomes fragmentary throughout 30 years, and many blocky and island-like patches emerged.展开更多

Along with the social economy high speed development, our country has entered the informationization, the networking, digital age, more and more people rely on computers to carry out the activities, the computer has completely integrated into the people work, study and life. At the same time, the rapid development of general information society makes the connection between the science and technology is more and more closely. From education itself level, skills contest for the establishment of the talents training goal of vocational education and general correction, through the interaction between higher vocational colleges to establish the corresponding talent training basic scheme.
