The effect of herbaceous vegetation cover on soil hydrology was analysed by means of rainfall simulation (63 mm h − 1; m 2) in reclaimed soils derived from opencast coal mining (a nonsaline and clayloam textured spoil) in centraleastern Spain. A total of 75 simulation experiments were conducted at three different times throughout the ...
Normalized Difference Vegetation Index. The NDVI is a dimensionless index that describes the difference between visible and nearinfrared reflectance of vegetation cover and can be used to estimate the density of green on an area of land (Weier and Herring, 2000). From: Environmental Research, 2018. Related terms: MODIS; Near Infrared; Rainfall

Effects on Weather and Climate. With vegetation covering about 20% of our planet, it''s no surprise that plants affect climate. However, it is surprising how much plants affect weather. Plants process and release water vapor (necessary for cloud formation) and absorb and emit energy used to drive weather.

Aug 24, 2014· Vegetation is an important part of the environment but may be subjected to disturbance in areas close to coal mines. This results in a slowing of the rate of biomass growth, which is caused by fading of vegetation. Simultaneously, carbon stored in vegetation is constantly released, weakening vegetation ability to act as a carbon sink. Indirect release of carbon during coal mining processes is ...
In Advanced Remote Sensing, 2012. Introduction. Fractional vegetation cover (FVC) is generally defined as the ratio of the vertical projection area of vegetation (including leaves, stalks, and branches) on the ground to the total vegetation area. FVC is an important parameter used to measure surface vegetation cover; additionally, it is an important index for researching the aerosphere ...
Vegetation succession or state and transition models for rehabilitated gold tailings dams have to be developed because such models are essential for land management of revegetated systems and to make more conclusive statements regarding sustainability of the vegetation cover.
Primary Causes of Deforestation. Deforestation is the state of clearing trees and vegetation cover by man for various reasons. Some of the reasons for deforestation include farming, construction, settlement, mining, or other economic purposes.
