This paper established sustainable land resources evaluating indicators fit for hilly area in Sichuan Basin, Southwest of china, and evaluated the case of sustainable land management of Lezhi County from 1990 to 2.01. The result showed that the land resource sustainable utilization ability in Lezhi County is belong to Second level （better sustainable）. Secondly, this paper diagnosed some years obstacles of sustainable land management of Lezhi County from base period to goal period and compared the obstacles factors in the indicators system. There were 16 indexes orderly become major affect factor to land sustainable utilization of Lezhi county in indicator system, of which there are 8 obstacles indexes exist both in 1990 and 2.01. The value of obstacles degree of five indicators exceeded 5 in 1990, but in 2.01, only two indicators＇ values were more than 5.

By means of combining auto-extraction with manual interpretation, the current distribution information about cultivated land is obtained. The distribution information of 1992.is extracted from the dynamic polygons of 2.02. The monitoring mini-system of the cultivated slope land is established. In the system, detailed surveys, focused on the resources of cultivated slope land, are carried out. The results indicate that the area of the cultivated slope land is very large. Meanwhile, there are lots of cultivated steep slopes with gradient above 3.°. The areas of steep land cultivated had been slowly reduced from 1992.to 2.02. At the same time, the pressures of returning farm land to forestry are great in all counties. The conflicts between population growth, insufficient grain supply and stagnant economic development sharpen increasingly. It is inevitable to improve the agricultural structure.

In the present study, formalin-fixed feces, oli-gonucleotide fingerprinting and SRY-gene based sexing were used to construct a family net for giant pandas in the Tang-jiahe Natural Reserve and to assess contemporary gene flow (migration) in this population. A total of 12. fecal samples were attributed to 3. individuals (2. females and 15 males) that were then analyzed for family relationships. Based on DNA fingerprints, the deduced family net revealed the fol-lowing facts: (i) First-order relatives possessed similarities from 50% to 90%, and similarities between unrelated indi-viduals or distant relatives were as high as 77%, indicating that the Tangjiahe pandas are characterized by high genetic similarity; (ii) 15 matings were identified and 5 ones oc-curred between close relatives, implying that there is poten-tial for inbreeding to impact the pandas; (iii) four mating pairs and 5 offspring presented long distance migrations, demonstrating the intra-reserve habitat is continuous; (iv) four pairs of full sibs (also female-male dyads) dispersed short distance and all of them gave birth to highly inbred offspring, reflecting long distance migration is vital for in-breeding avoidance; (v) 17 adult individuals dispersed short or moderate distance and formed three clusters on the land-scape, indicating that it is necessary to find out whether there is a negative factor impacting the pandas.

利用1990年TM数据和2.0 0 0年ETM数据,以农牧交错带的阴山山地中段为研究区,分析1990～2.0 0 0年土地利用类型的空间分异规律,重点探讨各土地利用类型中耕地、林地和草地的变化过程。研究表明,耕地的转移流向主要集中于草地,而草地的转移流向又集中于耕地,林地消失区主要转变为草地。阴山北麓为草地向耕地转变的集中区域;阴山南部是林地向草地转变最为集中的区域;阴山中部土地利用类型相互转化相对较少。在土地利用的垂向变化上,耕地减少区域集中分布于海拔15 0 0～16 0 0m及170 0～185 0m ;而其他土地利用类型向耕地转变的集中分布区域大致在海拔170 0～190 0m范围;海拔16 0 0～180 0m为草地-耕地相互转移变化最为集中的区域;草地面积主要在海拔14 5 0～16 0 0m范围增加,在16 5 0～180 0m范围内减少;林地除在海拔2.0 0 0～2.2.0 0m范围内与非林地相互转变大致持平外,在其余地区均发生退化。海拔180 0m和海拔2.10 0左右是本农牧交错带山地土地利用类型波动最为集中的两个分布区

陡坡耕地的水土流失对生态环境和农业可持续发展构成双重压力。退耕还林是促进人与自然协调,推动农业可持续发展的有效途径,但应避免退耕还林工程规模的盲目扩大。退耕还林的规模应根据自然条件、生态功能定位并考虑粮食安全保障以确定。地广人稀的金沙江中上游、盆周山地是长江上游最重要的水源涵养、水土保持功能区,其退耕还林规模可适度扩大,但川中丘陵区、三峡库区人口稠密,退耕还林不应过分追求规模,退耕后的林草地不应突破土地面积的40%。而退耕还林工程的实施更应注重模式的选择,防止一刀切,川中丘陵区、三峡库区退耕还林宜采用'旱坡地粮经弹性结构种植'技术,建立坡地农林复合系统,逐步实施退耕还林。

汶川地震诱发的大量崩塌和滑坡不仅直接为泥石流活动提供松散固体物质,还可能造成沟道堵塞。沟道内的堵塞坝虽然不像主河道上的堰塞湖那样造成大范围灾害,但溃决后却会引发大规模泥石流,给人民生命财产和基础设施等造成严重危害。以四川省安县高川乡甘沟为例,说明其造成泥石流的危害特征及防治对策。通过对甘沟自然环境背景条件的分析,发现甘沟具备泥石流暴发的地形地貌和降水条件;流域内地震诱发的崩滑体不仅为泥石流的形成提供丰富的松散固体物质,还造成沟道堵塞,形成堵溃型泥石流。甘沟已建的排导槽存在过流能力不够、槽底和侧墙已基本被破坏、弯道处未考虑超高、沟内未布置拦挡工程等问题。目前沟内由于松散固体物质充足,在一定的降水条件下,仍会再次暴发泥石流。针对甘沟的具体情况,提出了修建拦挡、重建排导槽并结合预警预报措施的防治对策,并对重建排导槽的过流断面进行了优化设计。

On May 12. 2.08, an earthquake of 8.0 magnitude on the Richter scale and its numerous aftershocks devastatingly hit Wenchuan County and its nearby region along the Longman Mountains in Sichuan province, china. The heavy ruined area was up to {2.,000km2.and 1{2. of its land surface was denuded by the extremely terrible quakes. The mountain collapses, landslides and debris flows induced by the earthquake not only scared the landscape at the immense scale, but also poured L66-billion-m{2.sediment combined with offscourings and rubble into the Yangtze River and its breaches. This amount of sediments is {2.times more than the normal amount discharged into the Yangtze River, and will significantly increase sediment transportation of rivers and decrease storage capacities of reservoirs downstream. The dramatic increase in sediment load will imperil the engineering safety and impact the operation of the giant Three-Gorge Hydro-power Station if no proper prevention measures are taken.

Ten major factors have been selected to judge the degree of disturbance from human activity and the corresponding relationship of the impact on soil and water loss in Sichuan province. Correlation analysis has demonstrated that stock-carrying capacity, percentage of land reclamation, population density, GDP per capita, mineral modulus and percentage of forest coverage are the 6 most relevant human activity factors. The analysis on the degree of disturbance has shown that population pressure, excessive or unreasonable activities in development of resources and destructive behavior of humans are the main causes of soil and water loss. Consequently, solving the various problems in the negative activity of humans and regulating human behavior are the first tasks that should be tackled in the conservation of water and soil. In the new era, the prevention and rectification of soil and water loss are measures based on the foundation of the ecosystem, which is a kind of management strategy for sustainable development. The foundation of this method is made up of the system innovations and breakthroughs in terms of aims, philosophy, measures, and aspects of the prevention and rectification of soil and water loss, simultaneous advance from the conceptual, policy, spatial, technical and mode levels and system integration on the treatment strategies.

针对雅安大相岭以南为亚热带湿润偏干季风气候区(汉源、石棉),以北为亚热带湿润季风气候区的气候特点,将雅安分为南部和北部两个亚区,从气候、土壤、灌溉、地形条件入手选择评价指标,并以不同灌溉条件的选择和海拔分级体现南北差异。采用层次分析法确定各评价因素权重,用指数和法计算各评价单元的综合分值,最后采用均匀内插法,进行分等定级。评价结果表明,雅安市耕地后备资源以三等和五等居多,其土壤类型以暗棕壤、沙黄泥土、淋溶紫色土、砖红紫色土为主。针对耕地后备资源特点,建议对耕地后备资源开发利用时,应根据后备资源质量等级及其限制条件,采用不同的开发手段;对有较严重限制因素的耕地后备资源,宜暂缓开发。
