Studys On Relation Of Rural Erengy And Water Resource Base In The Mountains Regions Of East Liaoning Province

Liaoning Province is one of the lacks water resources place in our country, Xinbin is theupriver of Dahuofang Reservoir, Guanyinge Reservoir and Huanren Reservoir, which is theimportant water supply base and the headwaters self-restraint areas of central cities inLiaoning Province, is the biggest green natural cover of mountains regions of east LiaoningProvince, is the central cities work agriculture and lifes use the water of important headwatersbase in Liaoning Province. Pay attention to the rural energy of Xinbin County and theconstruction of the headwaters bases, have the important realistic meaning and profoundhistory meanings.Contrast experiment between biogas manures and fertilizer, study on the effect of thecorn growth, yield and farmland path flowing water quality. The research results showed thatthe various economic characters were improved obviously, the yield and income wasincreased, the ecosystem equilibrium was promoted, after solid biogas manure used for basefertilizer, liquid biogas manure used for applying fertilizer. The corn uses the biogas manurescan show the increment the pure income; make devotion produce at the same time than theexaltation. At the meantime availably the biogas manure, can solve the rural energy, thedecontamination rural environment, and expand the fertilizer source, keep the ecosystembenign cycle. 2005 is a plentiful of rain year, the farmland path discharge compare greatly,handled the farmland path flowing water quality to experiment to provide the beneficialcondition for the variety fertilizer. The result indicated that uses biogas manure density'sflowing water of TP, TN and NO₃-N is lower than use to fertilizer. Contrast experiments toexpress that the corn uses the biogas manures ratio same period together the qualitycommensuration of use to fertilizer can reduce the density the path flowing water in TP, TNand NO₃-N. Make add fertilizer can increase the farmland soil TP, TN and NO₃-N at the sametime the form path flows to move.Xinbin County makes use of mature rural renewable energy technique, biogas, biomassgasication and solar energy etc economical great deal of increase firewood. Annually can theeconomize firewood 137680t, equal to protection the forest of the 4593.29hm². The forestvalid possession water quantity computes with the 1559.2 m³/hm²·a, then making use of the augmentative self-restraint headwaters of the village energy technique to measure to 7.16×10⁶m³/a. Carring out the equal to conservancy wood of various stanza of technique measurefirewood total amount to store to measure about the 146273 m³, equal to economize thestandard coal 49686t, amount to 20870000 yuan. Applied the original technique of new abilityto protect headwaters self-restraint wood's base of the eastern mountain area availably,improved the ecosystem environment and farmer living environments consumedly.Because the biogas solved the person and the animal excrement pollution bring by therun off water of the village, thus resolved the village to flow into the fluid matter problem ofthe reservoir, The biogas fertilizer to go into the farmland, flowing to the farmland path willnot produce the pollution,so the biogas the ecosystem function performance of the pond.
