摘要: 区域和景观尺度上的生态建设是指一定地域、跨生态系统、适用于特定景观类型的生态建设,即实行科学的生态系统管理和优化环境的建设工程.近年来国家实施了一系列重大的生态工程项目,如天然林保护工程、部分地区退耕还林还草、内陆河流域的生态调水等,取得了显著的效果.加强区域生态建设,维护国土安全已成为国家的战略需求.依据不同类型区的特点应实行不同的生态建设战略,如生态敏感区、脆弱区和高人口密度的生态压力区,可分别实施以生态安全保障、生态负荷调整和生态秩序重建为重点的生态建设战略,调控人类活动,实行有序开发,统筹人与自然的和谐发展.面对转型期的国家需求,我国景观生态学的发展迎来了挑战与机遇并存的重要契机.研究的关键议题包括:景观生态安全格局;土地利用与生态过程;人类活动胁迫下的景观变化;区域开发人类活动生态影响的定量评价;区域生态安全评价与预警;景观生态建设的模式设计与优化组合.

Abstract: The eco-construction on regional and landscape scale is the one which can be used to specific landscape and intercrossing ecosystem in specific region including performing scientific administration of ecosystem and optimizing environmental function.Recently,the government has taken a series of significant projects into action,such as national forest protection item,partly forest restoration,and adjustment of water,etc..Enforcing regional eco-construction and maintaining the ecology security of the nation have become the strategic requisition.In various regions,different eco-construction should be applied,for example,performing ecological safeguard measure in ecological sensitive zone,accommodating the ecological load in ecological fragile zone,etc.,which can control the activities of human being,so that,sustainable development can be reached.Facing opportunity and challenge in the development of landscape ecology,we have some key topics:landscape pattern of ecological security,land use and ecological process,landscape changes under human activity stress,quantitative evaluation of the influence on human being activities,evaluation of zonal ecological security and advance warning of ecological risk,and planning and optimizing of model in landscape eco-construction.

Key words: Eco-construction, Ecological security, Region, Orderly human activities, Landscape ecology
