| dc.description.abstract | This thesis explores the Miyun Reservoir Watershed’s soil condition and
the current situation it faces now. Miyun Reservoir is located in northern Beijing
and has more than sixty years of history. It is the primary water source in Beijing
and was listed as a first-grade water source protection in 1985. The reservoir has a
maximum surface area of 188 square kilometers, and it is shaped like an
equilateral triangle. For a better sustainable development, the government and
each department began to plan and survey Miyun Reservoir in 1951. Nowadays,
the scale of watershed treatment development is getting bigger and bigger, and
this place has received more and more attention. By doing literature reviews and
analysis from the database, this thesis discusses the factors that affect the soil
condition changes in various watershed compositions, such as land-use types, soil
properties, soil organic matters, topography, and water areas. Different
components can affect soil moisture, chemical elements in soil, and the degree of
soil erosion from all aspects. At the same time, it also faces the pollution
problems, which leads to a decrease in water quality and balance of the ecosystem
there. More policies are implemented in the Miyun Reservoir, and it becomes
more and more important for better environmental protection and tourism
development. | en_US |
