To develop short-rotation industrial plantation is an useful way to alleviaten the crisis of forest resources China and is useful for the coordination of the contradiction between economic and ecological use of forests. Recently, a lot of land used for developing the short-rotation industrial plantation are of low soil fertility, and the productivity of successive plantation on these lands is decreasing because of the degradation of soil fertility, largely due to the limitation of natural, social, and economic conditions. For consuming up a lot of soil nutrients, the short-rotation industrisl plantation could not absorb enough inherent nutrients from soil for its normal growth. It takes long time to restore soil fertility by biological ways such as mixed cropping and rotation of crops etc., and it is difficult to increase the soil fertility in the near future by these ways, so plantation fertilization, like the application of superior seeds,is necessary to cultivate the short-rotation industrial plantations.

发展短轮伐期工业用材林是缓解我国森林资源危机的有效途径之一,并有助于协调森林的经济利用和生态利用矛盾。受制于自然、社会、经济条件,日前发展工业用材林地区不少土壤肥力不高,养分比例失调;连栽人工林地力衰退异常明显,生产力下降;短轮伐期工业用材林养分消耗大,已有林地肥力不能满足其需求,而混交、轮栽等生物措施恢复地力过程缓慢,难以解决近期林地肥力不足矛盾,故林木施肥与良种选育一样,是培育短轮伐期工业用材林必要的基础技术措施。

There are many international rivers in northwest China, but main rivers are three; Ertis River, Di Riverand Akesu River. All of them are located in Xinjiang. Their common characteristics of water resources arerich of water, high diversity of river recharge, annual runoff with low Cv between years but varied greatly ina year. Based on its water resources, natural and economic conditions of the region, Ertis River should devel-op livestock husbandry as a main estate. Livestock, commercial grain products base shold be esthblished inDi River basin for Xinjiang and whole China, to form an industrial system of fabrics of wool and flax, leatherprocessing. In Akesu River, superiority should be given to establish cotton (special for plush cotton), food(special for high quality rice) base. Meanwhile, for sustainable development, people should pay great atten-tion to balanced ecological system and scial ?economic development. For this purpose, part of water re-sources should be served for ecological use and to build an artificial oasis economical system in the region.

西北地区国际河流众多,但主要有3个流域,即:额尔齐斯河、伊犁河及阿克苏河。它们都位于新疆境内,水资源的共同特征是:水资源丰沛、河川径流补给多样化、径流年际变化Cv值小而年内变化大。根据3个流域的水资源情况及自然经济情况,额尔齐斯河应以发展畜牧业为主导产业;伊犁河流域建成新疆乃至全国的畜产品基地、商品粮基地,形成以毛、麻纺织、皮草加工等为主的工业体系。阿克苏河流域要发挥自身优势,建设棉花(特别是长绒棉)、粮食(特别是优质水稻)基地,此外,为实现可持续发展战略,必须重视生态环境,要从总水资源中划出生态环境用水,建立人工绿洲生态经济系统。

This paper presents basic water resource and environment issues in the arid regions in the northwest of China. The first part reviews the water resources situation. The major water resource in the arid region in Northwest of China is surface water. Runoff distribution and relative features are the second part. There are many characteristics of surface water, such as heterogeneity of temporal and spatial distribution, diversity of runoff alimentation, and frequent exchanging between surface water and groundwater. At the third part, as is the most important part of this paper, the ayther studys the general eco environment situation in the arid regions in the Northwest of China through three typical inland watersheds. The situation is improved in the oasis but worsening outside oasis. Worsening cases include land desertification, glacial recession, lake drying up, river drying up in the lower reaches, higher frequency of dust devil, large area degradation of natural grasslands and natural vegetational cover damage. Water is needed to meet these challenges. At last part of this paper, a suggestion is given to the eco environment construction in the arid region. The suggestion is that water use should be divided into two parts: for ecological use purpose and for national economics use purpose, respectively. As to different typical cases of eco environment deterioration occurred in the lower reaches of Tarim river, Erjina region of Heihe river and Minqing region of Shiyang river, these water use insights should be dealt with carefully with different stress respectively.

西北干旱地区的水资源主要是地表水。地表水具有时空分布不均、河川径流补给来源的多样性和与地下水转换频繁等许多特点。西北干旱地区的生态环境在人工绿洲内部有所改善 ,但在绿洲外 ,正在进一步恶化 ,包括土地沙漠化、冰川退缩、湖泊干涸、下游河道断流、沙尘暴频次增加、天然草地大面积退化、天然植被遭到破坏等。这些问题都需要用水来解决。当前生态环境恶化的典型事例有 3处 :塔里木河下游、黑河额济纳地区和石羊河民勤地区
