    Dabieshan mountain area in west Anhui lies to the transition zone of subtropical moist and semi-moist monsoon climate. It is rich in species of biotic resources. But forestry, the main resource there, has been atrophied seriously. Now the local people are looking for extension arid substitution for resource conversion in their living and producing. The basic model of resource conversion is: resource-product-commodity-money-resource. During the earlier stage of the model, the emphasis should be laid on development and utilization, and the later should be laid on protection and extension. Each link of this model has a certain substitute in different time and space. So the efficient measures should be adopted to compose a proper model in order to ensure the peasants in this mountain area to go out of their poor life and become wealthy quickly.

    The Gudong Oil Field, with an area of 68 km2, is located to the north of the mouth of the Huanghe River. Considered from the viewpoint of geomorphology, it is in a land-sea transitional zone.This land was formed during the past decade by the shifting of the tail channel of the Huanghe River and the deposition of the sediment carried by the river. Since 1976, the Huanghe River has changed its tail channel from the Diaokou Tiver to the Qingshuigully, through which it now empties into the Laizhou Bay.The natural environment of this region is very complicated and there exist a lot of potential disasters in the oil field and the surrounding area, such as stormy tides, the flooding of the Huanghe River, the erosive retreating of the coastline, etc. All these could threaten the security of the oil field. If some of these potential disasters happened simultaneously, it would be extremely dangerous to the oil field.For the safety of the Gudong Oil Field, the author puts forward the following suggestions:1.Reinforcing the dykes by broadening their widths and meanwhile increasing their heights to 6.0 m above sea level in order to protect the oil field from demages caused by exceptional stormy tides and the flooding of the Huanghe River.2.Planting Spartina townsendii (Rice Grass) on the beaches as vastly as possible to reduce wave action, slow down the current speed, and protect the beaches; building a breakwater of 5.5 m high along the high-tide line to protect the coast from erosion.

    The relationship between forest and hydroresource is discussed in this paper. Author holds that whether or not forest can increase precipitation and runoff deponds on the behaviour of fopest-hydroresource system that includes six subsets, such as forest, hydrology, soil, geography, meteorology and climate. A model of producing runoff is suggested and pionts out that some area of forest can produce more runoff than that of on fourest on certain condition, and the optimal hydroresource system must meet four criteria: 1. .don't bring about flood; 2. don't bring about soil erosion; 3. don't disturb local natural ecosystem; 4; produce hydro-resource as much as possible. Then, the effect of forestoon precipitation is analyzed, forest can change space distribution of precipitation and increase possibility of regional precipitation, because of two characters of forest as boundary layer of atmosphere: 1. "soft"; 2. intense exchange between fored and atmosphere. These are two forms of increasing precipitation. At last, several suggestions on the method for research in forest-hydroresource system are made.

    ON EXPLOITATION AND THE STRATEGY OF MARINE EDIBLE ORGANISM RESOURCES IN CHINA
    Chen Feng

    After a brief introduction to the resource organisms in the China Sea, the author made aa overview on the history of exploitation of the organism resources. It was pointed out that the harvest yield had increased greatly with the increase of fishing intensity before the middle 1970's, however, since then, the amount of yield has decreased, in spite of still growing catch, intensity. The reasons causes for this discrepancy are over-exploitation of conventional fishery resources in the shallow shelf areas, pollution (mainly oil pollution in the coastal waters), and others, such as changes in environmental variables and red tides, among which the influence of the first is much greater than that of the other two. The following would be suggested for the better use of the resources:1)Make further study on marine ecosystems, which would greatly contribute to the rational exploitation and the management of the resources.2)Paff attention to resources off the coastal waters of the China Sea, in which the fishery stress on heavily exploited resources would be diminished and a stabilized fishery would be mainlained.3)Practise farming and ranching of the sea, especially multiplying some organisms in the lower trophic levels of marine food chain, which would also speed up recovery of the collapsed resources.

    Coastal sandy soil is an important land resource that has to be improved urgently in Guangdong Province. It is widespread, large in area and has a direct effect on the raise of the living standard of the local inhabitants, the economic development and the improvement of ecological environments. Coastal sandy soil is mainly distributed in Hainan Island, the western and the eastern Guangdong. The formation of it is closely related with coastal landform, river hydrology and climate. A large number of mud and sand carried by rivers and surface runoff, under the different actions of tide, wave and wind, makes outer bar and sand beach form and develops gradually. According to its differences of soil-formation age and soil characteristics, coastal sandy soil can be divided into four subgroups: mobile, half-fixing, fixing and cultivated coastal sandy soils. Their common characteristics are (1) that they are sandy so that water and fertilizer can lose easily and (2) that nutrition is lacking and soil are poor. The improvement and utility of coastal sandy soil should be (1) building shelterbelts; (2) developing multiindustry; (3) improving and using uncultivated sand land; (4) spreading organic fertilizer in order to improve sandy soil; (5) building water conservancy projects and (6) developing tourist resources.

    For associating with the realization of "The Outline of Natural Protection of China", we compiled the atlas of natural protection in China. It results from developing of modern science and is a new category in the field of thematic map. This paper expounded the importance and purpose of compilation in the view of natural protection. It has showed this atlas is comprehensive and especially in its renewable natural resources. According to mapping scopes it divides into atlas of nutural protection of the world, nation and region. Then, based on mapping contents it divides into comprehensive, thematic and regional atlas-of natural protection.In compilation of this the natural protection atlas of China, we have proposed 6 conditions in selecting subject and structure of the atlas. Most of opinions is that the atlas included 4 parts: 1. Prefatory maps. 2. Maps of natural resources and natural protection. 3. Maps of regional protection and natural protection area. 4. Pictures and items.We have described in this paper the features of mapping as follows: 1. The atlas has special theorectical base of mapping. 2. The atlas has more comprehensive features. 3. The atlas has a given authority. 4. The atlas has difficulties in uniformity. 5. The atlas is concerned with some maps of dynamic change. 6. The atlas has many scales, including large, medium and small. 7. The atlas has presented the deversity in the show forms.

    The distribution of economic shellfish on shallows all depends on it's environmental conditions. In order to estimate the distribution of upper resources, it is necessary to do normal plot servey as commonly mentioned used. But to research the natural factors on a grand scale, the means of grand scale control must be used.In this paper, by using of person-to-machine conversational proccessing, the data came from satellite CCT had been retrieved. And some informations about the water body with eddies and highly concentrated mud-sand in Huanghe River estuary were obtained. Compared with the data investigated in situ, the result showed that emergence and trasfer of eddy in this area comes and goes regularly. Then taking the habit of Area subcrenata into consideration, we confirmed that the diffusion of the mud-sand from Huanghe River to the sea has a direct impact on the distribution of Area subcrenata both in the estuary and it's neibourhoods. Finally the prediction about trend and range of Area subcrenata field for the coming 20 years in the research area had been made.
