摘要:
景观空间格局是生态系统或系统属性空间变异程度的具体表现，它影响着各种干扰的传播、物种的运动、土壤侵蚀等诸多生态现象。对重庆市巫溪县与璧山县生态修复示范区的土地利用景观进行空间格局分析。研究结果表明：（1）巫溪县的主要土地利用景观类型为灌木林地和山区旱地，璧山县则主要为丘陵区水田、旱地及有林地；（2）璧山县植被覆盖度较好，其自然生态系统较人工生态系统面积比例比巫溪县大；（3）巫溪县有占全县面积0.7%的裸岩石砾地及7.8%的坡度大于25°的旱地，表明巫溪县人为活动形成了大面积的坡耕地；（4）巫溪县复杂的山地地势及受干扰的退化系统，形成了其斑块面积变异性大、形状不规则、破碎化程度高的景观特点。
Abstract:
The landscape spatial pattern is the concrete presentation of eco-system and spatial variance extent of system attributes, which affects the transmission of various disturbances, the movement of species, soil erosion and lots of other ecological phenomenon. By analyzing the landscape spatial patterns of land use in Chongqing ecological restoration area including Wuxi and Bishan county, the results show: (1) The main landscapes of Wuxi county include shrubs and mountain dry lands, while the main landscapes of Bishan county include hill paddy field, dry land and woodland; (2) The vegetation covering rate of Bishan county is higher than Wuxi county by 7.87%, which represents that the natural eco-system area is much larger in Bishan county than that in Wuxi county; (3) There are 0.7% barren lands and 7.8% dry lands with 25° gradient in Wuxi county, which means human activities have shaped large area of cropland; (4) Owing to the complicated mountain terrain and disturbed degraded eco-system, the landscape characteristics of Wuxi county land use include great patches area variance, irregular shape and high fragmentation extent.
