Due to the severe restrictions of natural conditions and ecological environment,high-altitude mountainous areas usually become the " hard bones" in the battle against poverty. xueshan Township,Luquan Yi and Miao Autonomous County of Yunnan Province,located in the alpine valley of Jinsha River,is a major township with wide and deep poverty,and the incidence of poverty is up to 45. 00%. In recent years,xueshan Township has insisted on the battle against poverty,made effort to develop the Codonopsis pilosula industry,and successfully developed a road to poverty alleviation through C. pilosula industry,and formed a unique industrial poverty alleviation model by the end of 2018,the incidence of poverty dropped to 0. 74%. Based on field survey and interview,this paper analyzes and summarizes the specific practices,main results,practical experience and promotion and application measures of the poverty alleviation model of C. pilosula planting industry in xueshan Township,in the hope of providing certain reference for the targeted poverty alleviation in similar areas in Yunnan Province and other provinces of China.

Oriented by ecological,production and living functions of land,this paper analyzes the status of land use in xueshan Township,Luquan County,Yunnan Province using the method of assignment.The land is classified into general production land,production and ecological land,general living land,living and production land,living and ecological land,general ecological land and ecological and production land.The result is compared with the classification system of the second national land survey.In theory,the classification system of ecological land,living land and production land is constructed.Taking xueshan Township,Luquan County,a typical alpine valley area of Jinsha River as an example,based on the survey data on the changes of land use in xueshan Township in Luquan County in 2016,this paper analyzes the distribution of ecological land,living land and production land in xueshan Township.The results show that in xueshan Township,ecological land(including general ecological land and ecological and production land)has the largest proportion(54.84%)in area,followed by production land(including general production land and production and ecological land)(44.41%),and living land(including general living land and living and production land)has the lowest proportion(only 0.75%).In overall,the distribution of production land and ecological land in xueshan Township is not reasonable enough.For example,the proportion of dry land with a slope bigger than 15°and serious oil erosion in the township is currently 79.23%,among which,the dry land with a slope bigger than 25°and particularly serious soil erosion accounts for 52.88%.Therefore,it is necessary to gradually take measures to convert cultivated land into forests and further optimize the structure and spatial configuration of ecological land,living land and production land.

As one of the most fragile alpine plateau and canyon areas in China,the upper reaches of the Yangtze River are the key areas of ecological construction in China.It is also a key area for poverty alleviation in the country.Therefore,it is necessary to take into account the dual goals of poverty reduction and ecological environment construction,and explore a win-win road of ecological construction and poverty alleviation in line with the reality of the upper reaches of the Yangtze River.Taking xueshan Township,Luquan Yi and Miao Autonomous County,Yunnan Province,which is located in the poor mountainous area of the upper reaches of the Yangtze River as an example,based on many field investigations and existing investigation and statistical data,this paper analyzes the current situation and main problems of land use in xueshan Township,and then puts forward measures and suggestions for rational utilization of land resources in xueshan Township.This can provide a necessary reference for the next implementation of rural revitalization strategy and ecological construction.

GEOLOGICAL SIGNIFICANT OF SPOROPOLLEN ASSEMBLAGE IN THE xueshan FORMATION

引用

地学前缘 2000年第S1期7卷 151-151页

作者： Shi He,Wang Chengshan, Ma Runze,Wei Xiangui,Li Xianghui,Li Yong(Chengdu Institute of Technology, Chengdu 610059, China)

The xueshan Formation is a set of red coarse clastic deposit of land facies consisting mainly of lithic sandstone, pebbled sandstone, conglomerate, intercalated with siltstone and mudstone. It is distributed in the eastern part of north Qiangtang Basin, and overlies conformably the Suowa Formation bearing marine fossils. It is very difficult to find valuable fossils from the xueshan Formation excepting rare bivalve fragments and prints.We collected a few spore and pollen samples from the middle part of the xueshan Formation in Tuonamulematianbao section, Shuanghu, in 1997, when we made geological survey for petroleum and nature gas. Some fossils of spore and pollen were obtained from these samples. They are: Cyathidites minor, Toroisporis sp .., Todisporites minor, Lygodiumsporites subsimplex, Cicatricosisporites ludbrooki, C. sp ., Psophosphaera sp ., Chasmatosporites minor, Classopollis annulatus, C. clssoiddes, C. minor, Cerebrropollenites carlylensis, Callialasporites dampieri, Quadraeculina anellaeformis, Pseudopicea variabiliformis.
