Four types of forests including coniferous forest,mixed broadleaf- conifer forest,broadleaf forest,and shrub land were selected in Kunming Songhuaba Water Resource Protection Area to compare their water conservation capabilities. The capacity of canopy interception,the capacity of litters water- holding,...
and the maximum water holding capacity was found in 1 800plants/hm2,the reached maximum value was 2 868t/hm2;capillary porosity,capillary water storage capacity and total porosity had no obvious rules;(3)with the increase of the density of Pinus tabulaeformis,water conservation index increased,...
According to the intensities of human activities, water body was classified into natural ponds, ornamental ponds, natural creeks and sight-seeing creeks. Based on calculated Trophic State Index (TSI), we can get conclusion that the trophic status of different water body types all exceeded the ...
Water pricing can reduce the use of groundwater by irrigated agriculture. Price elasticities along the groundwater demand curve vary considerably. Instruments in addition to pricing schemes are needed to reduce water.关键词: Groundwater Dynamic programming Agricultural policy Pricing ...
In pig production, when the pigs drink water from some types of drinkers, it is obvious that some water that is sprayed from the drinkers will quickly fall into both the ground and the mouth of the pigs, and then the water falling into the ground will bemixed with waste and increase ...
Grasslands cover around 40% of earth’s surface3, and are crucial as repositories of biodiversity2. However, the protected areas destined to grasslands reserves are insufficient for conservation purposes. Thus, deepening our knowledge regarding biodiversity responses to different land-use types developing...
There are various types of pollution i.e. air, water, land, noise, industrial, soil, light, thermal etc. and they are categorized based on the region of the environment which they negatively impact, contributing to the multiple causes of pollution. Accordingly, each and every type of pollutio...
