Rural Landscape Promotion Strategy from the Perspective of All-for-one Tourism:A Case Study of Luyuan Village,Yuan'an County

Al-for-one tourism plays an increasingly important role in the development of national tourism,and rural landscape is endowed with multiple functions in all-for-one tourism pattern.After Yuan'an County was listed as the second batch of national all-in-one tourism demonstration zones,the establishment of al-in-one tourism puts forward higher requirements for the planning and promotion of rural landscape in Yuan'an County.By analyzing the status quo of rural landscape construction through landscape cultural characteristics,landscape differentiation and landscape management mechanism,combined with the current style of Luyuan Village in Yuan'an County,the paper discusses the promotion strategy and implementation approach of rural landscape in the perspective of all-region tourism from natural ecological landscape,settlement life landscape and economic production landscape,in order to bring new thinking for the improvement of rural landscape in China.

融合表达乙醇酸氧化酶和过氧化氢酶转基因马铃薯的表型分析

在叶绿体内创建光呼吸代谢支路降低光呼吸的损耗,必然会对植物的光合作用、氮同化和逆境响应造成影响,并最终导致植物生长发育及形态结构的变化。本研究通过在马铃薯叶绿体中融合表达乙醇酸氧化酶(Glycolate oxidase)和过氧化氢酶(Catalase)来分流光呼吸产生的乙醇酸,以期提高生物量和产量。结果表明,转基因植株的株高、叶面积、有效叶数和单株薯重与野生型相比均有所提高。同时,由于叶片形状、有效光合面积、有效叶数和株高等因子的变化,部分转基因株系出现块茎畸形和薯重降低的现象。

国家农业公园生态停车场设计及应用——以公安县天露湖为例

本文以湖北省公安县天露湖国家农业公园生态停车场的设计为例,以美丽乡村建设与国家生态文明理念为大背景,研究时下在建设国家农业公园时,如何利用生态化景观设计规划国家农业公园停车场,以期达到解决公园停车问题与呼应国家农业公园生态建设理念的目的,为下一阶段我国其他国家农业公园停车场的生态建设提供参考。
