    Sustainable development is the theme and direction of economic development in China for present and 21st century, and it is the theoretical basis of guiding the sufficient and rational use of natural resources. Deep researches of the objective law of sustainable development may help us to follow the right way of sustainable development of economy consciously, to give full play to the role of deploying the natural resources rationally by socialist market economy system,and to guide the proceeding of economic reform deeply. At last ,on the basis of sufficient and rational use of limited resources,our national economy will be promoted to go forward along the way of sustainable ,rapid and healthy development.

    THE PROBLEM OF LACKING WATER IN CITIES OF CHINA AND ITS MITIGATIVE WAYS

    The crisis of water resource is an inriportant knotty problem which puzzles many countries of the world. Particularly, the lack of water in cities becomes more and more severe. At present,there are 300 cities in China which lack water. In the 30 cities having a population of more than one million this problern is especially striking. The problem of lacking water has become one of the important restraining factors of economic development and construction in cities. The conditions of water resource in China are not superior. The water resource is more insufficient in large areas of the north of China ,where the speed of economic development of many cities surpasses the carrying capacity of local water resource. In the future, it should be that raising the utilization benefits of water, adopting vigorous measures to tap new water source, improving the repeated utilization rate of the production-use water,and controlling the pollution of water. Also it should be that making the technique and economy policies to inspire the economic use of water, supporting the transformation of the water economizing equipments, and adjusting the structure of property. In the cities which lack water the development of the industries that demand great amount of water should be limited.

    The progress of biotechnology, especially of gene engineering at home and abroad is introduced with plenty of practical examples in this paper. And the potential threats of biotechnology to the security of human beings are expounded from the following aspects:ethics,the damages to the health of people and to the environment,and so on. Finally,some constructive suggestions on the legislation of biosafety are proposed.

    CONSERVATION AND SUSTAINABLE USE OF WILDLIFE RESOURCE
    Jiang Zhigang
    1995, 10 (4):  332-338.  doi: 10.11849/zrzyxb.1995.04.004

    This paper first reviews the definition of the sustainable use of wildlife resource as a renewable resource. Then it looks into the cases of wildlife conservation and exploitation in Africa, North America, Europe , Australia and New Zealand. The noticed items include the recovery of once endangered elephants in Zimbabwe, the participation of local people in wildlife conservation in Southern Africa, the evolution of wildlife management system in North America,the importance of hunting to the economy of Western Germany, the game ownership and hunting licenses system of European countries, the significance of transforming the pastoral animal industry into deer industry in New Zealand and the management of kangaroos in Australia. It also reviews the traditional wildlife managernent ideas in ancient China and outlines two examples of over exploitation of wild species in modern China.Finally, the relationship between wildlife resource conservation and exploitation is discussed. It points out that the wildlife resource use in human history should be divided into four eras:the era of early exploitation,the era of over exploitation,the era of conservation and recovery and the era of sustainable use. However, due to the different characteristics of particular country and specific species,there are no universal rules guiding the management of wildlife resource. Now the wildlife resource in China is in the era of conservation and recovery.

    THE MULTI-OBJECTIVE OPTIMAL SUSTAINABLE USE OF BIOLOGICAL RESOURCE
    Guo Zhongwei
    1995, 10 (4):  339-345.  doi: 10.11849/zrzyxb.1995.04.005

    In this paper, the theory and method of multi-objective optimal sustainable use of biological resource are suggested on the basis of the theory of optimal control. When the yield of the biological resource is determined,not only the economic benefits and the capacity of population's recovery but also the effects of yield on environmental and social benefits are considered. The factors including those which reflect the environmental, biological, economic and social benefits are taken as the aims of optimization. In order to apply the theoretical optimal yield to an concrete biological system, the thought and method for meking the strategy of satisfactory sustainable yield are also suggested. As a case study, the multiobjective optimal sustainable use and the strategy of satisfactory sustainable yield of Waterhyacinth are discussed.

    AN EXPLORATION ON THE ECOAGRICULTURE CONSTRUCTION OF A COUNTY ZONE AND THE SUSTAINED DEVELOPMENTAL WAYS──A CASE STUDY IN MIANZHU COUNTY
    Hu Daize;Yang Chengfu
    1995, 10 (4):  346-356.  doi: 10.11849/zrzyxb.1995.04.006

    The ecoagriculture is a sustained agriculture which can use the agricultural natural resources perpetually. To construct the ecoagriculture is to consolidate the basis of sustained development of national economy. A county zone is a primary unit which has relatively complete socio-economic structure and function. It has relatively strong selfdevelopment and self-regulation capabilities. To study the ecoagriculture construction of a county zone has universal significance. This paper takes Mianzhu County as an example. According to the ecological characteristics of its regional resources and on the basis of three-year investigation and research ,we set up the general conception of the sustained development of a county zone and the optimal structural models of the sustained development of different small ecoeconomical area. This county's agriculture has developed continuously and got preliminary effects.

    A STUDY ON THE DEVELOPMENT AND UTILIZATION DIRECTION OF THE LOW-LYING SALINE-ALKALI WASTELAND IN THE YELLOW RIVER IRRIGATION REGION IN NINGXIA
    Yao Yulong
    1995, 10 (4):  364-371.  doi: 10.11849/zrzyxb.1995.04.008
    Abstract ( )   PDF (396KB) ( )   Save
    There are more than one hundred thousand hectares of low-lying saline-alkali wasteland which remain unused for a long time in Ningxia. Through integrated evahiation of local resources conditions and comprehensive comparison of different developing-utilizing models,this paper suggests that the best way to exploit the wasteland is to set up a stereoecoagricultural system by digging pools to breed fish and constructing tableland for cultivation. This system will be helpful to the development of rural economy and the estabhshment of fishery bases in Northwest China.

    The planning and device of landscape ecology (PDLE)is an area eco-planning method whose theoretical basis is the principle of landscape ecology. It sets forth corresponding construction schemes and countermeasures. Its main duty is to create an area landscape ecosystem which can develop continuously. The fundamental steps and ways of PDLE are a progressive realization process that proceeds from the ideal goal device, the functional planning and device,and the structure planning and device to the utilization and device of concrete units.

    This paper describes the status quo and the change situation of the relationship between population and land in Sichuan Province.It analyses the causes of changes through quantification method, briefly reveals the effects of changes on agriculture, and then puts forth the countermeasures which way mitigate the contradiction. This paper lays emphasis on analysing the causes of changes of the relationship between population and land,particully the changes in recent times, in order to clearly recognize them and accordingly take the effective countermeasures to mitigate the contradiction.
