The map is compiled by some of the mathmatical models that is established according to the quantiative relations between the stand density of slash pine and the different factors of tree measuration, on the basis of data of 220 plots of slash pine in Guangdong, and the law of stand density effect.

用全省范围内调查所得的220块标准地作为编图、检验材料，以林分密度效应规律为基础，根据湿地松林分密度与林分各测树因子之间的数量关系，建立各种数学模型，编制出广东省湿地松人工林密度管理图。

The results were as follows: After the slash pine stands cover-overheaded, the average DBH and crown diameter are very negative correlative to stand density, the average high of branch and high of tree are a certain extent correlative to stand density; high stand density can be a certain extent accelerate high growth, but the effect is limited.

结果表明：湿地松人工林林分郁闭后，林木平均胸径、平均冠幅与密度呈极显著负相关；林分平均枝下高、平均树高与密度有一定程度的相关性，高密度一定程度上可以促进林木的高生长。

本文根据语音信号的混沌本质，利用分形理论研究了汉语连续语音中的音节分割问题，提出了基于方差分形维数的音节分割方法，并详细分析了该方法的性能，它能很好地解决了无声与有声、浊音与清音间的分割问题，但很难解决浊音间的分割问题，当浊音相连且过渡段较短时，该方法无法实现它们之间的分割。

The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study
