摘要：
本文利用景观生态学格局分析方法。从重庆的这几个地区实际情况出发，再辅以多种参考信息，得到这几个地区景观的周长及面积等基本形状数据。对这些数据进行计算，得到各种景观的内缘比、分维数、景观多样性指数、优势度指数、景观分离度、景观变异系数等景观格局指标，比较1999年和2004年这几个地区景观格局变化。最后结果分析表明:研究区的植被覆盖景观大部分在减少; 各研究区景观整体的边缘长度，从1999年到2004年，5年期间均呈现降低趋势; 1999-2004年期间，景观整体的斑块密度都在减少, 说明各研究区景观的破碎化程度降低.说明本研究区的生态环境还不是很完善,需要进一步的改善和加强.

Abstract：
This paper used analysis of landscape ecology pattern, and obtained the basic shape data such as the girths and acreages of various landscapes of several towns from the actuality of these towns in Chongqing combined with multiple references. Through calculation of these data, the author obtained many landscape patter indexes such as the interior-to-edge ratios、the fractal dimensions, the diversity indexes, the dominance indexes, the separation indexes, the coefficients of variation etc. The landscape pattern change of these towns from 1999 to 2004 was also compared. The final results showed that most of the plant-covering landscapes in the research plots are reducing, and the edge lengths of the landscapes in each research plots exhibited declining trend from 1999 to 2004, so do the patch densities. The results suggested that the landscape fragmentation indexes are reducing and the ecological environment is not perfect in all the plots, therefore they need further modification and strengthening.
This text makes use of the view ecology structure and form analysis method.Set out from heavy this a few circumstances with actual region for celebrate, then assist with various reference informations, getting this a few weeks of view of region long and the area wait the basic shape data.Carry on the calculation to these datas, get various view of inside the good luck compare, cent 维 number, diverse sex index number, the advantage an index number, view separation degree, the view variation coefficient of view etc. the view structure and form index sign, compare 1999 and this a few view structure and form of region variety of 2004s.Finally result analytical enunciation: research the area plant to be overlay view big part at reduce; Whole edge length of each research area view, from the from 1999 to 2004,5 years the period all presents to lower the trend; 1999-2004 years period, the whole spot a densities of view all in the decrease, explain that each research area view falls in pieces to turn the degree to lower.The ecosystem environment that explains this research area is not just very perfect, needing the further improvement and strengthenning.
