Dynamic monitoring of golf course land in Beijing based on remote sensing technology

Abstract

In order to study the change dynamics of golf course land in Beijing nearly 30 years, firstly, we corrected and registered the geographical coordinates of TM image data in different time by ERDAS software, and enhanced the images to classify the images by using the supervised classification and unsupervised classification method, at the same time, reference with the Google Earth maps and the actual survey, and then extracted the information of the land change of golf course under the ARCGIS. The results indicated that over the past 20 years, the total areas of golf course land that underwent changes during the periods 1987-1998 and 1999-2009 respectively were from 185.49 Ha to 337.41 Ha and from519.75 Ha to 5275.98Ha. The dynamic change of golf course land in Beijing was quite obvious, and showed an increasing trend. In the initial period (1987-1999), the growth rate was 6.57%, in the rapid development period (2000-2003) and in the illegal development period (2004-2009), growth rate respectively was 31.02% and 62.42%. According to the transition matrices of golf course land change in Beijing for the period 2000-2009, it found that the transition area of golf course land from other land was very different: 1013.31ha from Built-up land, 534.24 ha from Woodland, 162.9 ha from Lawn irrigation, 377.01 ha from Grasslands, 1559.34 ha from Cultivated land and Orchard, 1628 ha from Other land, corresponding transferring rates were 19.21%, 10.13%, 3.09%, 7.15%, 29.56% and 30.86%. The conversion from Cultivated land and Orchard to the golf course land were the main transition. It could be concluded that the development process of golf course land had occupied the large Cultivated land and Orchard. Show more
