该文将空间炸点向量扩展为维时空向量,建立了考虑时间因素的动态射击效率模型.该模型可用于分析毁伤程度随时间的变化规律,比较不同发射法的优劣,确定炮火突然猛烈所需的最初炸点密度,解决最佳射击时域的最有利火力分配等,为理论研究、仿真实验及方法论证等提供了新的参考思路.

Fire is a common natural phenomenon in terrestrial ecosystems such as forests andstppe.

Fire is a common natural phenomenon in terrestrial ecosystems such as forests andstppe. In this paper,we researched the influence of Fall burning and Spring burning on thetotal above-ground biomass and the biomass of Gramineae,Allum,Compositae,Legumi-nosae and other herbs in Leymus chinense steppe,At the same time,we also researched theinfluence of burning on the quantity and growing status of Leymus chinense which was adominant population and Stipa grandis as well as Caragana microphylla which was un-favourable for mowwing and grazing Then,we discussed mechanism of using fire to im-prove pasttire. After two years monitoring,statistics aid analysis,we got the main resultsas following:1. The total yield of pasture was mainly controlled by precipitation. Before and afterburning the yield remained stable. Their above-groud biomas fluctuated from 180g/m ̄2 to200g/m ̄2 in normal harvest years. 2.After burning,the yield of grasses was increased by 25-45%than that of un-burned site.。In burned and unburned communities the yield of grasses showed similar in-creasing tendency from the begining of growing season to the middle of July.,The yield ofgrasses reached 80-120g/m ̄2 by the middle of July. After then,the yield of grasses of un-burned sites;tayed at this level, but that of burned sites increased continuously, whichgenerally reached 130-160g/m ̄2. 3.Burning had a remarkable promoting effect on the increase of Leymus chinensewhich was a high quality rhizome plant.In the middle and later of growing season,theaboveground biomass of L. chinense population in burned sites was 50-90g/m ̄2 more thanthat in unburned sites,which was more than that of unburned by 60-169%。4.In burned sites,the yield of high quality Leguminosae forage;increased a little,butthe yield of Allium generally keeped stable. 5.Burning can check the growth and reduce the quantity of Stipa grandis which is un-favourable for tanning and Caraganamicrophylla which is unfavourable for mowwing aswell as forages of Compositne and other herbs which have low utilizing value. The checkeffect was more obvious in Fall burning.In unburned community,the yield of Stipa grandisand Caragana microphylla were 30-50g/m ̄2 and 20-50g/m ̄2 after burning,the yield of sti-pa grandis decreased to 10-25g/m ̄2,and the yield of Caragana microphylla was generallyless than 10g/m ̄2. 6.The fire effects on improving pasture related closely to plant life form,growingform,the niches of populations. The influence of fire on the physical and chemical naturesof steppe soil was also a relative factor for pasture improving. According to these results,planning burning can increase the quality and utilizing value of pasture. So,buring is apasture improving method which costs a little aid easy.This method has a great applica-tion prospect.

本文研究了秋季火烧和春季火烧对内蒙古草原地带的羊草草原总产量优势种群羊草、大针茅以及小叶锦鸡儿数量与生长状况的影响。自1990年秋至1992秋经过两年的监测、统计与分析,主要研究结果如下:草场的总产量受大气降水的制约,火烧前后草场的总产量基本上保持稳定,中常年景的地上生物量变化在180──200克/平方米之间。火烧对优质根茎禾草一羊草的增长有显著的促进作用,在生长季的中后期,火烧地段上羊草种群的地上生物量比未烧地段高出50──90克/平方米,提高了600──160%。火烧地段上豆科草的产量略有提高,而葱类植物的产量基本上保持稳定。火烧可以抑制大针茅、小叶锦鸡儿和菊科杂类草的生长,减少它们的数量,其中以秋季火烧最为明显。在对照群落中,大针茅的产量为30──50克/平方米,小叶锦鸡儿为20──50克/平方米,火烧之后大针茅的产量减至10──25克/平方米,减少了50──60%,小叶锦鸡儿的产量一般低于10克/平方米。火烧对草场的效应与各种植物的生活型、生长型、种群生态位(对水分和养分等资源利用情况)等特点紧密相关。火烧对草原土壤理化性质的影响也是有关因素。综上所述,有计划的火烧可以提高草群质量和利用价值,是一种?
