文摘内容 By using landscape ecology theory and measure,structure,layout,function and resources utilization of urban and rural landscape during urbanization process had been studied;urban and rural landscape problems brought by urbanization and reasons causing them had been analyzed.In terms of rural landscape ecological problems,degeneration of natural and semi-natural landscape caused ecological unbalance,disorder of landscape pattern caused decrease of ecological environmental quality,disharmony between new and old landscape caused loss of native characteristic,contradiction between land and population became acute,land waste and pollution were serious and ecological environment had been damaged.In terms of urban landscape ecological problem,damage of regional ecological environment gave rise to decrease of ecological function,natural and cultural landscapes with significant value had been destroyed,urban green space constantly decreased and landscape fragmentation degree increased,urban layout lacked of planning which led to spatial development problem.On this basis,corresponding countermeasures had been proposed.It pointed out that,as for rural landscape ecological problems,it should pay attention to landscape ecological planning and adjustment of layout,coordinate regional comprehensive development by completeness principle,effectively coordinate all kinds of contradictions,intensify the effort for rural land arrangement,and develop construction of ecological network;as for urban landscape ecological problems,it should lay stress on reasonable planning of landscape structural proportion,establishing reasonable landscape pattern,effectively constructing urban green land and regulating ecological environment.
