General principles of land use：練習問題

Which farming practice involves growing the same single crop on a piece of land year after year without change?

Which environmental factor refers specifically to the physical features of the land, such as its slope and elevation, which can limit agricultural activities?

Why is forestry often the preferred land use for areas with poor soil fertility and high susceptibility to water erosion, compared to annual crop production?

What is a primary benefit of using a crop rotation system on a farm?

In the context of General principles of land use, which statement best describes the role of forestry?

How does a high altitude (a topographical factor) typically limit the types of crops that can be grown on a piece of land?

Explain how population growth affects the way land is allocated for forestry compared to food crop production.

Calculate the land-use efficiency ratio if an intensive farming system produces a specific output on a land area of \( 50 \) hectares compared to an extensive system requiring \( 250 \) hectares for the same yield.

Land use patterns are determined by human needs and the physical environment.
(a) Explain why population growth creates a need for more efficient farm planning and land use. (2 points)
(b) Identify two topographical factors that can limit the type of agricultural activities possible on a piece of land. (2 points)

Land use can be classified into various agricultural and non-agricultural systems. Crop rotation and forestry represent two distinct ways to manage land productivity.

(a) Explain the purpose of a crop rotation system and describe how it helps maintain soil fertility over time. (2 points)

(b) Forestry is an alternative form of land use. Describe two ways in which integrating trees into an agricultural landscape (agroforestry) can benefit a farm's ecosystem. (2 points)

(c) Identify one environmental factor that might lead a landowner to choose aquaculture over traditional crop production in a specific area. (1 point)
