摘要
为进一步改善太行山区生态环境条件 ,进行大范围的片麻岩山区再生景观生态建设 ,通过大量的调查 ,研究了太行山片麻岩山区景观生态构成要素的特征 ,以及太行山片麻岩区的景观生态类型的划分。结果认为 :片麻岩山区景观中的本底要素是山场坡面 ,根据坡度、部位以及坡向划分为上部缓坡、上部阳 (半阳 )陡坡、上部阴 (半阴 )陡坡、中部阳 (半阳 )缓坡、中部阳 (半阳 )陡坡、中部阴 (半阴 )陡坡、下部阳 (半阳 )缓坡、下部阴 (半阴 )缓坡 9个不同的类型。次生林是唯一的残余斑块 ,生态效益好 ,但分布数量少。干扰斑块主要有农田斑块、村庄建筑斑块和道路斑块。引入斑块主要有人工水土保持林、一般经济林和高效经济林。片麻岩山区景观生态的走廊是沟谷和河道。通过系统聚类 ,将该区的景观划分为荒山型景观、疏林型景观、经济林型景观、生态经济林型景观 4大类。生态经济林型景观的主要斑块是林地 ,森林覆盖率达 30 %～ 85%以上 ,生态协调功能较强 ,生态效益与经济效益较好 。
Through great lot of investigations,the characters of landscape ecological factors and the types of landscape ecology were studied.The results showed that:the matrix of landscape in the gneiss mountainous region of Taihang was hillside.According to the slope,the points and the direction of slope,we can divide hillside into 9 types:top slow slope; top southerly precipitous slope;top precipitious northerly slow slope;middle northerly precipitous slope;bottom southerly slow slope;bottom northerly slow slope.Secondary forest is the only remnant patch. The ecological benefit of secondary forest is high, but its quantity is small. The disturbance patch is farmaland,village and road patch. The introuduced patch is artificial forest of water and soil conservation, common economic forest and high-way. The landscape types were divided into barren hill, rare forest,economic forest and eco-economic forest landscape using cluster analysis.The main patch of eco-economic forest landscape is forestland.The rate of forest cover is above 30%～85%.The function of ecological adjusting is better,and the ecological benefit and the economic benefit are high. The eco-economic forest landscape is a perfect type.
