The Effect of Rural Comprehensive Food Planting Land Consolidation on the Ecological Landscape in Hilly and Mountainous

摘要

The effect of comprehensive food planting land consolidation on the regional ecological landscape is multifaceted. In this study, by comprehensive food planting land consolidation project in DaLu town to be example, comment on change of ecological environment and the rural landscape in research area. Shown that: (1) through rural comprehensive land consolidation, ecological environmental levels on the rise in the study area. (2) After the consolidation, the total number of plaques reduces 837, average shape index decreased to 1.98. Indicate the originally bent changeable plaques boundaries have become straight, conducive to mechanized farming; Also the arable land from 63.75% (3) After the consolidation, landscape fragmentation reduces 0.0008, aggregation indices increased 0.03, show through rural comprehensive land consolidation, making the overall pattern tends to be simple. But while this landscape pattern reduces species diversity and may accelerate the spread of pests and diseases. In summary, through rural comprehensive land consolidation, help to improve the productivity of the land, raise the level of regional ecological environment. At the same time, the effects of which on regional landscape ecological Positive and negative effects.
