摘要
本文运用景观生态学的理论和方法,在遥感和地理信息系统技术的支持下,应用ERDAS和FRAGSTATS3.3软件,分析了深圳市不同分区的绿地景观格局。结果表明随着人口密度的下降,各区绿化的数量逐渐增加。通过斑块密度、绿地分布指数两项景观格局指数及绿地率的分析可以发现:深圳市绿地分布的不平衡,福田区和南山区的绿地率低于40%,绿地景观格局较佳的有盐田区和龙岗区。
In this paper, landscape ecological methods have been introduced to describe and analyze quantitatively the greening landscape pattern, based on geqgraphical informa6on system software ARC/INFO, ERDAS and FBAGSTATS3.3. The greening coverage is increased with the decrease of the population density in the different districts. Through the two landscape ecological indices such as patch donsity, nearest neighbor index and greenbelt ratio,greening landscape pattern in Yantian and Longgang districts is better than other districts,greening distribution is imbalance and greenbelt ration in Futian and Nanshan district is less than 40 percent.
