Analysis and Control on Pattern of Landscape based on Planning Land Use Classification Taking a case study on Xinbei district of Changzhou,China

摘要

The landscape in Xinbei district of Changzhou was mapped based on planning land use classification by interpreting remote sensing images. Patch numbers, patch area, variation coefficient, shape index, fractal dimension index, Shannon's diversity index and Shannon's evenness index were selected to analyze landscape pattern in terms of structure, shape and diversity of the landscape. The result showed that cultivated land is largest land use type, covering 49.87% of total study area; thus, being the landscape matrix. Waters and waste land were most complicated in shape, while urban land is the simplest, showing the obvious diversity of the study area. Chunjiang town had the largest landscape diversity; however, Hehai Street had the least. Two kinds of distribution were made according to two secondary land use types. Based on various levels of land protection, study area was classified into 4 categories for land use ecological protection evaluation: strict, middle, moderate and mild. Based on different land use types, study area was divided into 4 categories for land use suitability evaluation of development: priority, moderate, controlled and unsuitable.
