中文摘要	以景泰县二期灌区生态经济型防护林建设示范村和景泰县沙漠化地区为例,对比分析了景电灌区荒漠绿洲景观格局的变化,结果表明,随着灌区的开发利用和灌区防护林体系的建设,景电灌区景观格局发生了很大变化,由开发前半固定、流动沙荒地为主的荒漠景观变成了荒漠绿洲景观,即防护林网保护下的农田景观、灌区边缘农田与沙地交接过渡区以防风阻沙林带为主的景观和灌区外围人工封育的半固定、流动沙地景观3种典型景观类型组成的荒漠绿洲景观,景观多样性增加,生态系统稳定性也随之增加.
英文摘要	Landscape changes or dynamics is one of the central research topics in landscape ecology. The object of this study was to investigate the landscape dynamics of the new oasis in the Jingtai electrical irrigation area in Gansu province. Taking the demonstration region for eco-economic forest-protective construction in an electrical irrigation areaf and a desertifying area, in Jingtai County as examples, the oasis landscape pattern was analyzed. The results show that some great changes in landscape pattern have taken place with the development and establishment of the forest-protective system in the electrical-irrigation area. The landscape pattern was changed from desert land dominated by semifixed and mobile sand to a desert-oasis landscape, which consisted of three typical patch types, namely farmland sheltered by forest network, transition area between farmland and sand dominated by a forest system giving protection from wind and controlling sand, and semi-fixed and mobile sand. Landscape diversity increased and ecosystem stability was enhanced.
