摘  要:城市绿地作为工业区生态系统中主要的自然成分和初级生产者 ,在改善环境质量、调节生态平衡、维持生态安全上具有不可替代的作用。近年来 ,城市绿地景观生态研究虽然得到普遍关注 ,但现有的研究多倾向于一般空间格局分析 ,针对不同功能区的绿地景观生态综合比较评价研究却少见报道。以武钢工业区为例 ,选用 IKONOS为主要信息源 ,结合外业调查 ,建立工业区绿地地理信息系统 ,以景观生态学理论为指导 ,从物种丰富度、群落结构、绿地类型斑块特征、景观异质性等方面进行了武钢工业区绿地景观生态学分析 ,并运用主成分分析法 ,对不同功能区绿地景观生态学作了综合评价 ,为区域景观生态综合评价提供一定的参考。研究结果表明 :工业区中普遍运用的是抗性较强的树种 ,种类较丰富 ,其中物种数量为 7~ 8的斑块出现频率及面积均最高。武钢绿化覆盖率为 30 .5 8% ,绿地破碎 ,主要由中小型绿地斑块组成 ,附属绿地是工业区绿化主体。公园绿地物种搭配最为丰富 ,绿化质量较高 ,其它绿地空间呈团聚状态分布 ,防护绿地形态格局比较简单 ,生产绿地分离度最大 (0 .718)。不同区域绿地景观格局表现差异显着 ,生活区绿地斑块规模普遍较大 ,绿化覆盖率高 (4 3.2 7% ) ,景观多样性高 (3.39) ;主厂区绿地破碎度为1.32 4 6 ,物?As the dominant natural component and primary producer, greenbelt system play key role on improving environmental quality, regulating ecological balance, and maintaining ecological security. Attention was paid to urban greenbelt landscape ecological research, especially to the spatial pattern analysis. However, relative research is under developed especially on landscape ecological comprehensive assessment. Based on remote sensing and the investigation in Wuhan steel & iron industrial district, greenbelt GIS is developed on ArcGIS software. And the greenbelt system landscape ecology is analyzed from such aspects as plant diversity, community structure, greenbelt patch character, landscape heterogeneity etc. Then landscape ecological comprehensive assessment of greenbelt is carried on in different districts. The results showed that the prevalent garden plants are tolerant species, and its species abundance is high. Patches with 7 species appear at highest frequency (12.2%), and patches with 8 species have largest area which constitute the 20.1% of total greenbelt. Wuhan steel & iron industrial district is covered by greenbelt at the rate of 30.58%, which is fragmentized and irregularly shaped, and comprised by little patches. And attached greenbelt is the principle part of landscape types, which occupies 45.57% of greenbelt area and 76.41% of number. Every kinds of greenbelt have different landscape pattern that public park has the largest average shape index (3.38) and most abundant species. Other greenbelt has the largest landscape connectivity index, whereas its spatial pattern is near to assembling distribution whose nearest neighbor index is 0.577. The spatial formation of green buffer is simple, and the separation index of nursery is largest. In living district, the greenbelt landscape is characterized by large patch, even distribution, high diversity and high greenbelt coverage rate, while the greenbelt landscape is characterized by small patches, heavy fragmentation and low species abundance in factor
