In this thesis , the effects of acid materials on calcareous soil were studied by using laboratory soil trial and pot experiments trail. The text studied effects of acid materials on pH value in calcareous soil ; studied effects of phosphoric acid (H2SO4 as control) on pH value and micronutrient availability ; studied relation between P and available Fe, Zn in plant; studied effects of acid material on growth of acidophilic plant.

The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

The results demonstrated that the intracellular pH change was different when the Hela cells was treated with different anti-tumor drugs, some would caused intracellular acidification, some would caused ntracellular basification, and some would barely caused pH change. The single living Hela cells uptaken with the ratiometric pH nanosensor was also imaged with laser confocal microscope, which were treated with anti-tumor drugs.

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.
