NA Ping-Shan, ZHANG Ming-Ru, XU Shu-Lin
2001, 9(3): 22-24.
Abstract(1054) PDF(919)
Abstract:
Based on the field observation and simulation in laboratory,the effects of frozen stagnant water (FSW) on ecoenvironmental construction of Northwest area were analyzed. FSW is seasonal solid underground water, formed by freezing effects in winter in the frozen soil layer of independent water and salt dynamics.It has positive and negative effects on ecoenvironmental construction. FSW generally increases the amount of water by 8%～25%.The maximum water content is 39.51%.The water content is 300% at frozen lumps on the ground. It is indispensable or even the unique water source for natural forest and manual vegetation lived through the winter, vegetation growth in spring, water metabolism, and also is a central factor of ecological balance in Three-North area. When the FSW content ＜5%，it brings about contabescence for natural forest and manual vegelation, and acceleration of desertification but when water content arrives at immoderate sturated state, some geological phenomena as frozen lumps on the ground, landslides, dents and salingation of swamplifotion are formed, thus accelerating the deterioralion and imbalance of ecology. The control of FSW content is very important to building the engineering of sustainable developing forestry and improving ecoenvironment in Northwest area.

2001, 9(3): 40-42.
Abstract(1518) PDF(1050)
Abstract:
Four years investigation showed that the farm microclimate has a great change under poplar-crop intercropping system. In comparison with the non-tree control, the average air temperature and wind speed in intercropping farm are decreased by 1.0～1.2℃ and by 32.1%～59.8% respectively, but the relative air humidity is increased by 4.1%～12.2%. And the change of farm microclimate leaded by near-mature poplar stand has the similar consequence. The tree shading degree, on the other hand, becomes more and more serious following with poplar growing. In order to maintain crop output, the intercropping duration will not over 6 years when the poplar spacing is about 20m, but it will prolong for 10 years when it is 30m. It is suggested that the poplar spacing between rows should be over 30m and its branches should be pruned regularly to ensure the stability and long-term of the intercropping system.

Abstract(802) PDF(939)
Abstract:
There are still some defects in the traditional wastewater biological disposal technology,when it has gone through 100 years' application. These defects are greater investment, much power and inconvenient management. In the wastewater purification system of varied organisms, wastewater is purified according to the metabolism of the food chain step by step. The system is composed of three disposal units of microbes, plants and aquatic animals. The organic matters in wastewater are digested and resolved into CO2,H2O,NH4+,CH4,PO43-,etc. by anaerobe in the first unit. When wastewater passes through the second unit, everyone of them except CH4 is absorbed by algae or plants and transformed into cells of plants by photosynthesis. In the third unit,the excessive microbes and algae are eaten by planktons or fish and transformed into animal albumen. Finally wastewater is purified, its effect can arrive at the level of third grade disposal. The wastewater purification technique of varied organisms is an ecological safe disposal technique to environment. It will be a new technique of 21st century. It has a good application foreground, especially is suitable for wastewater disposal in small town.
