It is well known that the mining industry produces a large amount of derelict land, and causes pollution of water loss and soil erosion as well as other environmental damage in china. As land is under pressure in china. it is now policy to restore or reclaim land despoiled by mining, the aim being to develop sustainable and healthy arable land ecosystems. This paper outlines the principles and approaches of ecological restoration, which have been adopted in Shanxi Province with reference to three typical surface mines. In the research, the principles of ecological engineering and ecological succession are considered as the critical theories of ecological restoration in mine degraded land. Meanwhile, the paper made a comparative research on main links of ecological rebuilding in three surface mines in Shanxi Province, which include new land construction, treatment of toxic substances, control of soil erosion, fertility management, irrigation, ecological planning and the establishment of legislation systems. As the research demonstrated, for successful restoration, new land construction is the fundamental framework, but it must be integrated with ecological engineering including ecological planning, the control of soil erosion and vegetation establishment and ecosystem creation in order to optimise land productivity and soil fertility. In addition, the establishment of the legislation systems and organization of administration are also indispensable aspects of ecological rebuilding in mined land.

Land-use change is an important aspect of global environment change. It is, in a sense, the direct result of human activities influencing our physical environment. This paper analyzed the land-use change in Northeast china.during 1985-2000 based on Landsat TM images. It divides Northeast china.into five land-use zones based on the dynamic degree model of land-use: woodland/grassland-arable land conversion zone, dry land-paddy field conversion zone; urban expansion zone, interlocked zone of farming and pasturing and reclamation and abandon zone. The findings include the obvious increase of cropland area, paddy field and dry land increased by 75 and 276 thousand hm2 respectively; urban areas expanded rapidly, areas of town and rural residence increased by 76.8 thousand hm2; areas of forests and grassland decreased sharply with the amounts of 1399 and 1521 thousand hm2 respectively; areas of water body and unused land increased by 148 and 514 thousand hm2 respectively. This paper also discusses the

Ecological suitability analysis is an important step in ecological planning. It applies the basis toestablish a sound development planning. In this paper, by applying multi-dimension niche concept, an eco-logical niche suitability (ENS) model was developed. The ENS model, combined with geographical informa-tion system (GIS) and spatial simulation, was used to analyze regional resources and environmental features ,and identify the suitability of regional resource and environment to regional development. An application ofthe ENS model in Taojiang agricultural land use planning is presented.

Rice (\%Oryza sativa\% cv. Jindao 1187) was grown in open_top chambers which contained ambient and enriched CO\-2. CO\-2 elevation stimulated rice tillering during early vegetative stage. However, panicle dry weight per plant did not change at maturity stage. Root biomass was enhanced by high CO\-2. Root / shoot ratio was increased under high CO\-2 at maturity, indicating more carbon allocation to the below_bround part in rice under high CO\-2.

Xinjiang’s oasis agriculture has made enormous strides over past decades. Structural adjustment of oasis agriculture sector has promoted production diversification. Xinjiang’s oasis agriculture sector is entering a new era. The era means more adjustments in oasis agricultural and rural economic structure so as to realize the sustainable development of agriculture. By summing and analyzing the main problems in Xinjinag’s oasis agricultural structure, such as raising farmer’s income, industry structure within agriculture, rural urbanization, pressure coming from market, agricultural environment degradation, puts forward the thinking, director and countermeasures to adjust oasis agricultural structure.

Using plant mini-Ti cosmid pEND4K, the cosmid genomic library of Sesbania rostratawas constructed. Sizes of plant DNA inserts in clones were 25- 33 kb. The restrictionmapping showed that different recombinant involved various types of plant DNA insert. 4clones containing leghemoglobin gene sequence of S. rostrata were obtained by in situ hy-bridization of colonies. The cloning of leghemoglobin gene sequence has been confirmedby plasmid DNA dot hybridization and Southern blot hybridization.

s: The planning area and developing area in china.s l29 national and 584 provincial development areas cover 8000 km2 and l500 km2 respectively. By typical field investigations we found that china.s development areas have the characteristics of abundant categories, excessive quantities, large scales and dense localities in coastlands, border areas and river banks. And their utilization have 4 features of mainly collecting and occupying agricultural lands, minor rebuilding of old city; mainly taking up cultivated lands, minor exploiting and utilizing barren mountains and bleak sloping lands; collecting and occupying lands at first, utilizing afterwards; using large quantities of lands but obtaining comparatively fewer benefits. According to the analyses, china.s development areas can be concluded into one of the four categories: constructed from cultivated lands, reconstructed from old cities, constructed from coastlands and islands, and constructed from barren mountains and desolate sloping lands. Their corresponding problems of unsuitable planning and distribution leaving cultivated lands unused, low remission price and chaotic management measures are analyzed in detail and the countermeasures are put forward. These include planning and distribution the lands in an integrated way, managing all these lands in a unified system. improving the growth pattern of their economy, and advancing their utilization and output ratios.

The sterility of Pingxiang male-sterile rice (Pins), possibly derided from a spontaneous mutation in Pingxiang fertile rice (Pmf), was previously reported to be controlled by a single dominant nuclear gene. It can be restored to fertility either by a dominant epistatic gene or by higher temperature treatment at the early stage of inflorescence development. In order to tag the genie male-sterile gene, Pms, Pmf and Ce 64, a cytoplasmic male-sterile restoring line without the epistatic gene for Pms, were used to construct mapping populations. Two segregation populations, "(Pms/Ce 64) F1s (sterile plant)//Pmf" F1 and "Pms//(Pmf/Ce 64) F1" F1, were simultaneously developed. Subsequently, the genie male- sterile gene was mapped between a simple sequence length polymorphism marker, RM228, and a restriction fragment length polymorphism marker, G2155, with distances of 14.9 and 2.6 cM, respectively. The tagged dominant genie male-sterile gene is temporarily designated Ms-p.
