Protective forest systems in China: current status, problems and perspectives

Article Abstract:

The status of protective forest systems established in the 1950s in China is discussed. The forests, which are unique in being multipurpose in nature, but are not well managed, are generally successful, cover 30 mil ha, make up about 10-13% of the forested area of China, and have a usable stemwood volume of 850 mil cu m, while contributing in economic, ecological and social ways to the country, despite some problems.

A global analysis of begetation fires using satellite images: spatial and temporal dynamics

Article Abstract:

An assessment of natural and man-made vegetative fires, usually concentrated in the tropical and sub-tropical belt of the Americas, Africa and Asia, is made using satellite remote sensing technology. This technology expands data collection from a regional and continental scale to a global scale. The spacial and temporal distribution of active fires can be analyzed using this technology.

Forest cover of insular Southeast Asia mapped from recent satellite images of coarse spatial resolution

Article Abstract:

Forest cover is mapped by unsupervised digital classification, which shows not only forest area extent and distribution, but also, the change in the forest cover through a satellite image. The results indicate that if deforestation continues at the same level, a lot of timber resources will be lost.
