Survey on Influence of Tourism Development on Ensuring Supply and Increasing Income of Farmers in Nyingchi

Tourism is an essential industry promoting economic development of Nyingchi and also plays a great role in national economy. Increasing people's income and improving living conditions are starting points of promoting tourism development. This survey indicates that tourism in Nyingchi develops rapidly,growth rate of tourists is slightly lower than growth rate of income,and per capita tourist consumption is also increasing. Comparative analysis indicates that tourist resources,traffic condition,tourism propaganda intensity,development intensity of relevant products,and seasonal factor have significant influence on ensuring supply and increasing income of farmers. Further analysis shows that low educational level,weak basic tourism knowledge,backward tourism sanitation,and lagging tourist service infrastructure are major problems and obstacles. Resource advantages of scenic spots,setting foot on structural adjustment of characteristic industry,developing specialized farmer cooperatives and leading enterprises,and deeply exploring intension of tourist culture are major approaches for ensuring supply and increasing income of farmers. In sum,it is urgent and important to strengthen ability of ensuring supply and increasing income in improving people's living conditions and promoting tourism development.

Photosynthetic Characteristics of Three Fig Cultivars in Nyingchi, Tibet

The photosynthetic characteristics of three excellent fig cultivars introduced, Branswick, Qingpi and Xinjiang Zaohuang, were compared in the paper, in order to provide reference for the cultivation and breeding of different fig cultivars in Tibet. The daily variation of photosynthetic parameters of the three excellent fig cultivars, Branswick, Qingpi and Xinjiang Zaohuang, which were introduced and cultivated by XiZang Agriculture and Animal Husbandry College in Bayi District, Nyingchi City, Tibet, were measured and compared. The results showed that the net photosynthetic rates (Pn) of three fig cultivars were Qingpi > Branswick > Xinjiang Zaohuang, and the daily variation curves of net photosynthetic rate were all of unimodal pattern. The daily variation curves of transpiration rate (Tr), water utilization efficiency (WUE) and efficiency for solar energy utilization (Pn/Par) of different fig cultivars showed unimodal pattern;the daily variation curve of intercellular CO2 content (Ci) showed decline pattern;the daily variation curve of stomatal conductance (Gs) showed bimodal pattern;Pn had extremely positive correlation with Tr, WUE, Gs, Par, Pn/Par and Ta.

Dynamic Changes in Per Capita Net Income of Rural Residents in Nyingchi City of Tibet

Through an in-depth analysis of the per capita net income of rural residents in Nyingchi City,it was known that the per capita net income of rural residents in Nyingchi City was increasing at high speed in recent 10 years. However,the wage income,household operating income,and agricultural income gap constitute the major factors influencing the gap of the per capita net income of rural residents in Nyingchi City. Finally,it came up with recommendations including promoting the reasonable flow of labor to the secondary and tertiary industries,increasing the wage income and transfer income of rural residents,accelerating the construction of small towns in rural areas,promoting the development of rural cooperatives,implementing the strategy of " benefiting farmers and strengthening tourism",promoting integration of agriculture and eco-tourism,promoting the development of modern agriculture,and expanding diversified production income of farmers.

Tibet's First Eco-Tour Villagein Nyingchi

Gongzong Village lies in mountains skirted by National Highway No.318 in Nyingchi. All the villagers have home telephones, earning the area the nickname of "telephone village". But the meaning of its real name in Tibetan is"bumper harvest of fruit" or "bumper harvest of grapes."Sprawling along the mountain slopes, Gongzong Village is a world of orchards. A stream fed by a gurgling fountain cuts through the village before meeting the Nying River.

NYINGCHI,THE NATURAL BEAUTY,AND THE BEAUTY OF NATURE

"This beautiful place",Nyingchi,refers to the beauty of mountain ranges,water,valleys,lakes,and even glaciers.No matter how it is defined or named in accordance with tradition, it will never be excessive to credit this place with the description of beautiful;such beauty is barely defined by words.

Nyingchi Revisited

In1951,When Tibet wonpeaceful liberation, PLAsoldiers reached a townwith only a few house-holds. As a token of thanks forthe PLA who strove to expandit, the town was named Bayi,or August 1,the day on whichthe People’s Liberation Armywas founded.

林芝市引进梨品种果实品质的综合分析与评价模型构建

【目的】在西藏引入不同优良梨品种,以调整区内梨果树种植结构,为推动西藏特色林果业发展提供理论依据。【方法】以西藏林芝市引入的9个梨品种作为试验材料,成熟后测定其12项果实品质指标。通过相关性分析和因子分析,建立基于因子分析、主成分分析、线性回归分析以及相似性分析的综合品质评价模型,并根据综合品质得分进行优良度排序,筛选出适宜林芝市种植的优良梨品种。【结果】9个梨品种的果实品质性状变异系数有所不同,其中果形指数的变异系数较大,单果质量、果实硬度、可滴定酸含量、固酸比和石细胞含量的变异系数均中等,果实横径、果实纵径、果心横径、果心比、可溶性固形物和维生素C含量的变异系数均相对较小。对9个梨品种的12项果实品质性状的因子分析,得知前4个公因子的累积方差贡献率达89.120%,其中,第1个公因子的贡献率为37.240%,主要反映果实大小和酸甜口感品质,第2个公因子的贡献率为20.658%,主要反映了梨果实的软硬程度,第3个公因子的贡献率为17.760%,主要反映了果实形状和维生素C含量,第4个公因子的贡献率为13.642%,主要反映了果实可食部分大小和果实糖含量。各品种间存在显著的统计差异(R=0.768,p=0.001),新梨七号与晚秋黄品种显示出最大的差异性。品种间在多维性状上的分布特点表明质量和横径被识别为分类的关键因素。经综合品质评价模型,得出9个梨品种在林芝种植后的果实综合品质得分高低排序为圆黄、华山、翠冠、中梨1号、初夏绿、新梨七号、翠玉、红太阳和晚秋黄。【结论】研究结果对指导西藏自治区内特色梨品种的选育和促进梨产业的可持续发展具有重要意义。

Thoughts on Pairing Assistance to Tibet for Promoting Agricultural High-quality Development in Southern Tibet from the Perspective of Agricultural Power

In the new era,there is an urgent need to further promote pairing assistance to Tibet,promote the simultaneous construction of a strong agriculture in Tibet and the China's Mainland,and compose a Chinese-style modernization.Southern Tibet,located in the southeastern part of the Tibet Autonomous Region,includes Shannan City and Nyingchi City,is a region assisted by four provincial partners including Hubei Province.This paper introduces the agricultural environment in southern Tibet,studies its agricultural characteristics,and analyzes the main issues of its pairing assistance.Taking forging the strong consciousness of the Chinese national community as the main line,the paper explores strategies for promoting agricultural high-quality development in southern Tibet through pairing assistance to Tibet from the perspective of agricultural power,and proposes some strategies,such as inheriting agricultural cultural heritage,promoting the upgrading of modern seed industry,enhancing the characteristic advantages of highland barley(naked barley)and animal husbandry industries,and developing edible fungi and cold water fish industries.

青藏高原东构造结林芝地热田浅部典型电性结构及热储关系

约40 Ma以来,受控于印度板块的俯冲及后期演化,青藏高原喜马拉雅山系东构造结成为了板块活动最强烈的地区之一;由于深部动力学过程中的浅表响应,该地区地热资源极为丰富。笔者等通过对两条音频大地电磁(AMT)测线进行数据处理与分析,查明了测点覆盖区域范围内二维电性结构及主要存在的深大断裂。依据电性结构推测研究区地下1 km深度范围内可分为4层,浅部低阻层为松散砂泥卵石层,下伏的中阻为砾卵石层,其下的低阻为砂岩、板岩、页岩强风化层,最底部的中高阻层推测为古元古界林芝岩群真巴岩组以片岩、花岗岩为主的地层。结合以往大地电磁测深及地震研究发现的地下10~20 km存在大规模近东西向展布且向上延伸熔融流变导致的低速高导体,推测可能是该地区深部热源所在。进一步通过对深部及浅部电阻率模型的综合对比研究,基于地热地质背景、电性结构特征,探讨了该地区的深部热源及热储关系。

西藏林芝蜂蜜与其他地区蜂蜜挥发性成分比较分析

[目的]探究西藏林芝蜂蜜的特征挥发性成分。[方法]采用HS-SPME结合GC-MS对西藏林芝、陕西秦岭、西藏山南、吉林长白山和云南香格里拉地区蜂蜜的挥发性成分进行分析,并结合化学计量学研究西藏林芝蜂蜜与其他4个产地蜂蜜挥发性成分之间的差异。[结果]5个地区蜂蜜中共鉴定了103种成分,其中西藏林芝蜂蜜61种,陕西秦岭36种,西藏山南49种,吉林长白山31种,云南香格里拉42种。林芝蜂蜜挥发性成分种类最丰富,主要以酯类为主,且含量占比较大,其他4个地区则以醇类和醛类占比较大。单因素方差分析发现不同产地间有45种化合物含量存在显著差异,正交偏最小二乘判别分析进一步鉴定出水杨酸乙酯、正己酸、辛烷、苯丙酸乙酯、戊酸乙酯、辛酸乙酯、苯乙醇和辛醛8种化合物是区别林芝蜂蜜和其他地区蜂蜜的关键物质,其中苯丙酸乙酯、戊酸乙酯和辛酸乙酯仅在林芝蜂蜜中被检测到。[结论]酯类物质对区别林芝蜂蜜与其他地区蜂蜜具有重要意义。
