Opis

After the 1998 flood of the Yangtze River, one of the world's most important rivers, environmental experts realized that, to control flooding, much more attention must be paid to vegetation cover on bare lands, thin forest land, and shrub-covered land in mountain areas. In 1999, an environmental monitoring project of the forests in 11 provinces of the Yangtze River basin was undertaken. This book reports on soil loss prediction and the successful practices of soil loss control in eastern China in recent years.

In recent decades in eastern China there has been great progress towards ecological restoration through reforestation of bare lands and steeply sloping cultivated land suffering from serious erosion. This book introduces several soil loss control models suitable for land use strategies along with  many techniques of reforestation with a focus on improving the living standards of farmers. These strategies include “local recycling,” which combines the use of trees (fruit trees, herb, bamboo), crops for feeding livestock, use of animal wastes for biogas and fertilizer, fish production, and a “large scale recycling,” fostering the interaction between the countryside of the mountainous areas and the urban areas in the lower elevations. The “local recycling” can alleviate poverty for farmers and provide fuel material that replaces dependence on twigs and tree litter, which in turn protects the reforested young trees from being harmed. The “large scale recycling” creates a more harmonious society and promotes the common health and wealth of the countryside and the city. This book presents the most comprehensive and successful models of reforestation in eastern China.
