描述:
he paper studies from the situation and feature of Agriculture
Tri-dimension Pollution in Yellow River Basin areas, and divides it into several regions according to
basin’s pollution feature by adopting the method of searching documents , research, systems analysis,
quantitative and qualitative analysis and so on, and analyzes the problem of Agriculture Tri-dimension
Pollution in Yellow River Basin areas from the view of tri-dimension and system by use of the theory of
Environmental value, Technology Value, Ecology, Circular economy , uses System Dynamics to track
dynamically the change in the future of the various variables in different modes and constructs the
system mode of agricultural tri-dimension pollution in Yellow River Basin, and simulates the system;
描述:
est region,
which c
ombined with the
water-saving, agricultural soil and water conservation techniques, and then taken "
drought
resistance, reduce erosion, increase efficiency" as a principle.
描述:
be given when fully and rational use of local
climatic resources such as solar radiation, heat and water, while other conditions (such as soil
fertility, carbon dioxide concentration, cultivation level etc.)
描述:
duction in the area is
restricted by disadvantageous natural resources and environmental conditions,
including low arable land area per capita, frequent drought events and a landscape
dominated by mountains. Forage crop rotation systems could improve soil fertility,
increase crop外eld and provide quality forage supplies for livestock production.
Additionally, their adoption is considered a suitable means to advance sustainable
agriculture development. In this study, the role and status of forage crop rotations in
Tianshui city were studied.
