依据城市生态景观学的相关理论,运用RS遥感技术及TM遥感数据,以广州为例,绘制出了相应的绿地系统分析图和统计表,研究了土地利用分类、特征及其绿地景观格局,并对景观丰富度等6种常用景观指数进行了分析。结果表明:在城市化驱动下,中心老城区缺乏宏观规划,景观破碎化程度严重;次中心城区景观聚集度较高,但缺乏生态节点联系。鉴于此,提出了城市景观格局的改善与优化建议。
依據城市生態景觀學的相關理論,運用RS遙感技術及TM遙感數據,以廣州為例,繪製齣瞭相應的綠地繫統分析圖和統計錶,研究瞭土地利用分類、特徵及其綠地景觀格跼,併對景觀豐富度等6種常用景觀指數進行瞭分析。結果錶明:在城市化驅動下,中心老城區缺乏宏觀規劃,景觀破碎化程度嚴重;次中心城區景觀聚集度較高,但缺乏生態節點聯繫。鑒于此,提齣瞭城市景觀格跼的改善與優化建議。

According to the theories concerning landscape ecology and based on RS technology and TM images, this article, taking Guangzhou city for example, draws out the analysis chart and statistical table of the green space system, studies land use classification, characteristics and the landscape pattern, and analyzes six landscape indices in common use to optimize the ecology environment. The results show that, under the promotion of urbanization, the landscape fragmentation become more and more serious because the centrality old city lacks of macro programming. In the meantime, secondary centrality urban area has a high contagion index but is short of the connection between different ecology nodes. In view of the facts, this article gives some improvement and optimization suggestions of urban landscape pattern.
