摘要:
选择洪河保护区及其周边为研究区域,充分利用历史图件、遥感资料和GIS技术反映保护区及其周边土地利用变化,并对保护区内湿地景观多样性进行分析.研究结果显示:(1)1983年以来,洪河保护区周边高强度的土地开发活动导致了湿地面积以60 km2/年的速度减少;(2)保护区内湿地景观多样性降低趋势明显,表明原有的保护区与周边之间明显的景观生态联系因土地利用变化而被强制割断;(3)保护区周边湿地景观严重破碎化以及土地排水活动是保护区湿地景观多样性变化的根本原因;(4)恢复保护区周边一定面积的湿地,维持保护区与周边区域适当的景观连续性,恢复保护区基本水文条件是维护保护区自然保护效益的有效途径.
Abstract:
Land use change of surrounding Honghe Nature Reserve in the past decades has been studied based on historical map s, remote sensing data and app lying GIS techniques. Detailed investigation on draining engineering around Honghe nature reserve has been conducted for this study. The results show that: (1) The high strength land reclamation surrounding Honghe Nature Reserve has p roduced 60 km wetlands lost every year since 1983; ( 2) decline of wetland landscape diversity in Honghe Nature Re serve indicated that the original relationship between Honghe Nature Reserve and its surrounding area has been isolated by land use change; (3) water recharge from watershed to Honghe Nature Reserve has been comp letely lost due to draining activities in the surrounding area. The phenomena has already seriously threatened biodiversity of Honghe Nature Reserve; (4) restoreing some area of wetlands in surrounding area of Honghe Nature Reserve to maintain the landscape connectivity with its surrounding area, and re storing hydrological condition of Nature Reserve are available app roaches to facilitate the conservation of benefits for Honghe Nature Reserve.
