    The present paper mainly disses the impacts of East and Middle-Route water diversion from the Changjiang River to the Huang-Huai-Hai Plains upon natal environment.1.Studies of the changes of water circulation and water resources as well as their relationships with biocycle, atmospheric circulation and geologic process are key problems concerning the impact of inter-basin water transfer on natural environment. The process With respect to the impact of water transfer on the environment can be Summed up roughly by the following model.Water transfer→changes of the original hydrological regime→changes of thenatural environment→changes of social economy.2.The impacts of any water transfer project on the environment., according to geographic regions, may be divided into three different regions with regard to issues, namely, the water-exported region, the region through ,which water is transferred and the water-imported region.The water-exported region, With the completion of the .water transfer, influence will chiefly occur at the initial point where water starts to be exported and at the lower reaches of the river below the initial point during low-flow period.The main influence of water transfer on natural environments are as follows. Possible intensification of sea water intrusion, the acceleration of the deposition of fine particles and the expansion of bars in the Chang-jiang estuary due to the decrease of runoff of Changjiang river in low-flow periods.3.The region through which water is transferred.It mainly refers to areas on both sids of the conveyance canals as well as to the surroundings of the .water bodies of regulation and storage that are involved .Water transfer of the East route will certainly exert some influence on the water quality and aquatic ecosystems of the lakes. 4.The water-imported region: Large quantities of water diverted from Changjiang River into the Huang-Huai-Hai Plains through the middle and East Roites will inevitably cause great changes on ecosystems of the Plains. The major problems to be ackled concerning impacts of water transfer on natural environment in the water imported region are as follows. The prevention of secondary salinization and alka-lization in irrigated areas and the influence of water transfer on climate in irrigated areas and their surrounding environments.

    本文主要讨论了从长江向黄淮海平原调水对自然环境的影响。 研究水分循环和水资源的变化及与之有关的物质循环的关系,是研究跨流域调水对自然环境影响的核心问题。调水对环境影响的过程,大体可归结为如下的模式:调水→改变原有的水文情势→自然环境的变化→社会经济的变化。 任何调水工程对环境的影响,均可按地理分区方法分为水量输出区、输水通过区和水量输入区。南水北调对水量输出区的影响主要在枯水期发生在输水点附近及其下游。输水通过区主要使输水渠两侧和蓄水体周围环境受到影响。大量长江水调入黄准海平原,在一定程度上将引起黄淮海平原生态系统的变化。

    This is the study on the interaction of wheat cultivars and leaf rust of wheat of two adjacent provinces.The interaction of 54 wheat cultivars of Hebei and Henan and 161 isolates of P.recondita f.sp.tritici of Hebei and Henan was studied.The result showed that there were considerable number of cultivars which were relatively resistant to leaf rust of both provinces in Hebei,while there were much fewer resistant ones in Henan. The average values of virulence frequency of rust population of either He- bei or Henan by cross inoculating the cultivars of one province with the rust of the other province were 53.8% and 53.0% respectively,indicating the virulence of rust population of two provinces on the whole is similar. However,as to the interaction of a particular cultivar and a particular rust isolate is concerned,Hebei isolates are more virulent toward certain cultivars,while the converse is true toward certain other cultivars.The authors suggest in order to obatin cultivars with broad spectrum of resist- ance,it is better to study the interaction of certain cultivars and rust population within a certain limited geographic region intensively rather than testing the varietal resistance by using artificially chosen races which may not be representative.

    本研究是用生物间遗传学的观点和方法,继续研究两个邻近省即河北、河南两省小麦品种与两省叶锈菌的相互作用。通过两省54个小麦品种与161个叶锈菌株的相互作用研究,可以看出在河北省已推广的品种中,如冀麦2号等的毒力频率值为100%,严重感染叶锈病。其他品种如丰抗8号等毒力频率值为22.5—29.2%,对两省的叶锈菌的抗性都较好。河南省已推广的品种中除百农3217和郑6辐的毒力频率值为66.7—68%属中度感病外,其余如郑州681等的毒力频率值为82.0—99.4%,都表现高度感病。用河北、河南两省叶锈菌株对两省小麦品种进行交互接种,两省的叶锈菌所表现的平均毒力频率值分别为53.8%和53%,说明两个邻近省的叶锈菌群体在总的毒性方面是相似的,但对具体的小麦品种,两省叶锈菌群体所表现的毒性可以不同。

    Weichang County of Hebei is located at a place where three physical geographic regions( i. e. Inner Mongolia , Northeast and North China regions )meet. There is abundant resource of wild plants in Weichang because of its geomorphology ,climat, soil and history conditions. The meadow steppe is distributed on the Bashan Plateau in the northwest of the county; In the slopes of the valleies and north and northeast slopes of low mountain, there is mixed forest of the coniferous and broadleaf tree of small areas. The forest - steppe is distributed over the rolling plateau area in the east of the county. There is mixed forest of the coniferous and broadleaf tree in the north and northeast slopes "of the mountains. And in the south of the county, there is the mountainous mixed forest . AH plants in the county belong respectively to 100 and more families, 300 and more genera and 1000 and more species or varieties.These plants are divided into 8 groups on the basis of use value: 1) General and special commercial plant; 2) The plants for water and wind erosion control ; 3) The plants for fuel forest;4) The plants for forage; 5) Medical plants; 6) The plants for foods and drinks; 7) The plants for industry raw materials ; 8) Ornamental plants. Those main plant names were listed in this paper.
