Many ongoing processes in today's landscapes impact our environment considerably. Thus, it is enormously important to gather information on qualitative characteristics of our landscapes in order to effectively counteract the negative developments.

The Hani terrace landscape located in the mountainous areas of Southwestern China has a history of 1300 years and is a classic example of human–environment harmony. This study investigates the spatial distribution and pattern characteristics of land cover in the landscape using geographical information system and remote-sensing techniques.

Conversion of native prairie land for agricultural production has resulted in significant loss and redistribution of soil organic matter (SOM) in the soil profile ultimately leading to declining soil fertility in a low-productivity semiarid agroecosystem.
