摘　　要：以东莞市高土步镇土地利用规划为例,预测小城镇尺度下土地利用规划实施前后的景观格局变化。结果表明,土地利用规划实施后,高土步镇内农业用地面积减小,工矿仓储用地、管理与服务用地、公园与绿地、交通运输用地的面积增加;农业用地、住宅用地、工矿仓储用地等零散、小斑块被合并,斑块数减少,形状趋于规则化;景观多样性指数和均匀度指数上升,优势度指数和破碎度指数下降,分布更趋均衡化,景观异质性提高。Taking land-use programming of Gaobu town,Dongguan city as an example,the landscape pattern changes before and after the implementation of land-use programming under the scale of small town were predicted.The results showed that,after the implementation of land-use programming,the area of agricultural land in Gaobu Town would be decreased,while the storage sites for industry and mine,management and service sites,park and green belt,land for traffic and transfortation would be increased;the fragmentary lands and patches of agricultural land,residential land and storage sites for industry and mine would be united,the number of patches would be decreased,and their shape would become more regular;the diversity index and evenness index of landscape would be raised,the dominance index and fragmentation index would be dropped down,the distribution of each patch class would become more even,and landscape heterogeneity would enhance.
