从宏观与微观视角,对比分析三工河流域两种经营模式下的农田景观特征,探讨形成这两种景观的原因。得出以下结论:①三工河流域农田扩张过程中,1989—1999年地方的农田增长起主导作用,1999—2007年兵团的农田扩张比地方更为明显,地方与兵团农业发展中的灌溉技术差距是决定两地农田规模扩张差异的主要原因;②土地使用制度的不同导致地方农田表现出小斑块、高密度的特点,而兵团农田则具有大斑块、低密度的特点;

从宏观与微观视角,对比分析三工河流域两种经营模式下的农田景观特征,探讨形成这两种景观的原因。得出以下结论:①三工河流域农田扩张过程中,1989—1999年地方的农田增长起主导作用,1999—2007年兵团的农田扩张比地方更为明显,地方与兵团农业发展中的灌溉技术差距是决定两地农田规模扩张差异的主要原因;②土地使用制度的不同导致地方农田表现出小斑块、高密度的特点,而兵团农田则具有大斑块、低密度的特点;③兵团作物种植受宏观调控影响显著,这与地方农户自主选择作物种植类型不同,由此两地农田内部景观格局也形成一

为了解沙尘传输过程中气溶胶粒子光学性质的变化,利用2001—2008年中国北方4个站点沙尘期间的数据资料,比较分析了沙尘源区与下游地区气溶胶光学特性的差异。结果表明,沙尘期间大量粗粒子对总消光具有强烈贡献,沙尘源区和下游地区粗粒子消光分别占总消光的85.2%和65.8%。沙尘期间沙尘源区与下游地区均表现出较高的气溶胶光学厚度;而源区的Angstrom波长指数明显低于下游地区,当沙尘暴出现时会下降到
