| 摘 要： | 采用CLUE-S模型模拟方法，对基于历史发展趋势以及“天然林保护工程”和“退耕还林还草工程”政策下2000-2020年间岷江上游地区土地利用/覆被变化进行了预案分析.结果表明：2000-2020年间，按历史发展趋势，作为研究区景观基质的林地面积将不断减少，而灌木林地和草地面积将不断增加，景观破碎化程度将不断加剧；“天然林保护工程”和“退耕还林还草工程”能够有效增加研究区林地面积，并使草地面积不断下降，同时能够扭转景观破碎化趋势，使景观格局向着更加优化的方向发展.

| Abstract: | By using CLUE-S model,a scenario analysis was made on the land use/cover change in the upper reaches of Minjiang River from 2000 to 2020,based on the historic development trend and the regulations of policies natural forest protection and grain for green. In 2000-2020,according to the historic development trend,the forestland area (landscape matrix) in the study region would have a continual decrease while the shrub land and grassland areas would be increased,and the landscape pattern would be more fragment... |
