摘要

Power transmission and transformation projects can cause certain changes to vegetation and landscape pattern, as they run through all kinds of landscapes. But Vegetation and Landscape Pattern assessment on its impact is weak in past studies, most of which focus only on theoretic summaries as well as qualitative assessments. Taking the 500kv Transmission and Transformation of Dagang-Chongzhou as example, this paper adopts landscape ecological method to assess and forecast the changes to vegetation and landscape pattern. Using the remote sensing and geographical information technology, the landscape of 500kv transmission and transformation of Dagang-Chongzhou were classified and changes in the landscape before and after the construction were analyzed. By research method of the comparative sample investigations, the indexes of plant species diversity and stability were investigated and analyzed. The study shows that if the project is put in practice, little changes will occur with respect to diversity, homogeneity of the regional vegetation and landscape pattern, and little influence will cause on primary regional vegetation and landscape pattern.
