自然占有

In recent years, Feng Kang has advanced a more natural and direct redu-ction, i. e. the reduction via Green's formula and Green's function.

近年来冯康又提出一种更自然而直接的归化，即从Green公式及Green函数出发将微分方程边值问题化为边界上的含有广义函数意义下发散积分有限部分的奇异积分方程，这种归化在各种边界归化中占有特殊地位，被称为正则边界归化，本文将这一理论应用于重调和椭圆边值问题，研究了其正则归化的性质，并通过利用Green函数、Fourier分析及复变函数论方法等不同途径求出了在上半平面、单位圆内部、单位圆外部三种区域的Poisson积分公式及正则积分方程，其离散化可用于实际计算。

Because personal and economic activities are regulated by the natural laws of the market through private law rather than through politics, victimless crimes, and crimes against the state are rendered moot.

Entomophagous bats are the valid natural enemies of pests because they prey on pests such as gnat and miller, etc. However, fruit bats are damnous for they eat fruit such as litchi, longan and banana, etc.

蝙蝠在该地区自然生态系统中占有重要地位，食虫蝙蝠捕食蚊、蛾等害虫，是控制害虫的有效天敌之一，食果蝙蝠对荔枝、龙眼、香蕉等水果造成一定危害。

From of old Ma Lan by our country working people wide to cultivate, in Confucius " domestic language ", of Qu Yuan " from coquettish ", of Li Shizhen " detailed outline of a book on Chinese medicine " the account that there are pair of Ma Lan in waiting, as admirable water and soil conservation, depasture, view and admire and officinal plant occupies position in the history and nature.

自古以来马兰就被我国劳动人民广为种植，在孔子的《家语》。屈原的《离骚》。李时珍的《本草纲目》等中都有对马兰的记载，作为优良的水土保持。放牧。观赏和药用植物在历史和自然中都占有一席之地。

The comparative study on vegetation background survey of the stationsand the comparison on level of phytocoenology on zonal habitats indicates thatthe diminishment of the numbers of families,genus and species,compositionof life types,diversity of communities and habitats,;and the increscence in theproportion of photosynthesis functional groups of C3/C4 plant,richness ofspecies,density of tussock and tiller,diversity of species,evenness,leaf areaindex,leaf area duration,dry matter production of communities alongside thelatitude increasing and the temperature decreasing;and the dynamic curve ofthe community productivity also tend to steadily increase along with thetemperature going up and the heat accumulation gradually in moderate-temperate steppe station from violent fluctuation along with seasonal badly-distribution of precipitation in warm-temperature steppe station;manifestingthat transformable tendency of productivity pattern of the community from morevigorous net assimilation,sparser and higher crops stricture of tussock and tiller,and possession on more resources by less species inclined to thicker in densityof crops,superior effectiveness of multi-leaves and pattern of multi-speciesresource sharing,reflecting that bigger disparity of the vegetationcharacteristics and the style of the community growth in the two differentthermal-type steppe stations owing to background of natural-historicenvironment and combination of water and heat.

内蒙古草原区两个不同热量型研究站点植被本底调查和显域地境群落学水平的比较研究表明：随纬度增加和气温降低，植物科、属、种的数目，生活型组成，群落类型和生境类型的多样性均趋于减少，而C3/C4光合功能群比值和群落的物种丰富度，株丛密度，物种多样性，群落均匀度，叶面积指数，叶面积持续时间和群落干物质生产能力均趋于增加，群落生产力动态曲线从随天然降水的季节分布不均而剧烈波动趋向于随气温逐渐升高和热量逐步积累而稳定增长，显示出两站点植物群落从较为旺盛的群体净同化作用、较为稀疏高大的群体结构和少数物种占有较多群落资源的生产力格局向较高的群体密度、优良的多叶性能和多物种资源共享的群落生产力格局转变，反映出在内蒙古草原区不同的自然历史环境背景和不同的温度条件及其水热组合状况影响下，两个不同热量型草原站点植被性质的分异特征和显域地境群落生长模式的较大差别。

There are more than 15,000,000mu plowlands in Ningxia, 2.5mu per capita; The lands in Ningxia Plains are fertile, Huanghe River passes through Ningxia for 397km, which provides convenience for irrigation, we have over 6,000,000mu irrigable high yields, it is one of the four irrigated area and 12 significant commodity grain production bases in China; Besides, there are plenty areas of uncultivated lands waiting for reclamation, one of 8 provinces in china which holds thousands arable land; the beef and mutton which are Islamic Muslim, and wolfberry, the grapefruit which can planted for making red wine, watermelon with Si and sand, potato, liquorice, and high quality of rice, etc.

第三，旅游资源丰富而独特，既有边塞风光的雄浑，又有江南景色的秀丽，被称为&中国西北的盆景&，中国10大类95种基本旅游资源中，宁夏就占有8类46种，自然风光旅游热线有沙坡头、沙湖、青铜峡、六盘山、星海湖等，历史人文景观有西夏王陵、华夏西部影视城、以及回族伊斯兰风情等。

As George Bernard Shaw puts it,"The maternal instinct leads a woman to prefer a tenth share in a first-rate man to the exclusive possession of a third-rate one." Despite the fact that humans are naturally polygynous, most industrial societies are monogamous because men tend to be more or less equal in their resources compared with their ancestors in medieval times.

正如George Bernard Shaw 所说，&母姓的直觉会导致一名女人宁愿选择要&一流男人&的十分之一，也不愿意要独自占有&三流男人&的全部&尽管说人类自然会选择一夫多妻，但是，大部分的工业化国家都是一夫一妻，因为那里的男性往往和自己在中世纪的祖先相比在资源方面要或多或少地更加平均化。

The development of man is realized by possessing nature, society and man himself.

人的发展是通过对自然、社会和人本身的占有而实现的。

With the expansion of the population and the frequency of the human's activities, the natural resources, especially the unrenewable resources are consumed greatly.

自然保护区管理在资源与环境中占有独特的地位，保护区管理中的许多问题是全球共同面对的&人-地关系&论题的反映。

Being one of environment sensitivity elements, land use occupancies consequence of environment study in monitor and sustainable development.

土地利用作为生态环境系统的一个敏感因子，因其受自然地理因素和人类社会活动的双重影响，在生态环境监测和可持续发展研究中占有非常重要的地位，因此，土地资源问题研究是当今资源与环境问题研究的核心内容之一。
