<p><b>OBJECTIVE</b>To conduct preliminary investigation to the species and reserves of medicinal plants in Huangfu Mountain, and to provide references to the general survey of those plants for medicine.</p><p><b>METHOD</b>Combined with global positioning system (GPS), the program of investigation with grid sampling was used in this resource survey of medicinal plants.</p><p><b>RESULT</b>After the preliminary investigation of the plants for medical use of Huangfu Mountain, it is found that there are 103 families with 313 kinds of plants. There are many medicinal plants and large distribution, such as Pseudostellaria heterophylla, Semiaguilegia adoxoides and Pinellia ternate.</p><p><b>CONCLUSION</b>Huangfu Mount, with so many different kinds of medicinal plants and comfortable environment for part of the medicinal plants to grow, could be developed as a base for planting Chinese herbal medicines.</p>

Spatial structure and geographic distribution of major active component in medical herb Dipsacus asperoides population / 中国中药杂志

To study the spatial structure and geographic distribution of major active components in medical herb Dipsacus asperoides population, in Guizhou province, the author obtained the asperosaponin VI content among 38 D. asperoides population points. Using spatial statistic and traditional statistic, the spatial variation pattern has been found. Combining the environment variables, it is tried to reveal the geographic distribution rules between group of major active component in medical herb D. asperoides population and group of environmental factors. The results show: the spatial structure of major active component in medical herb D. asperoides population is randomly distributed in global space, but has two aggregation points which have a high positive correlation in local space; environmental factors value for group of major active component in medical herb D. asperoides population has a large difference in the interior-group, but environmental factors value has a small difference in inter-group.

Research on reserves estimation method of wild medicinal plants resource for generous species based on spatial information technology / 中国中药杂志

Traditional Chinese medicinal resource survey method is time-consuming, strenuous, and having great human influence, the precision is not high enough. This paper, by using spatial information technology, carries on spatial sampling survey for wild medicinal plants resource for generous species to arrange the quadrat scientifically and estimate the suitable area, reserve precisely of medicinal plants. It not only improves the survey precision, but reduces the workload of field survey and provides scientific basis for survey method of pilot work on the fourth national traditional Chinese medicinal resource census.

Application of hyperspectral remote sensing in field of medicinal plants monitoring research / 中国中药杂志

The paper introduces the basic concept and characteristics of hyperspectral remote sensing, and analyzed the application of hyperspectral remote sensing in the field of plants research. On the basis of the research advances of hyperspectral plant study, paper also analyzed the key facts that effects the application of hyperspectral remote sensing on the some researches which include distinguishing species,monitoring growth and quality etc. It proposed a new ideas and methods for people to research medicinal plants.

Data validation methods and discussion on Chinese materia medica resource survey / 中国中药杂志

From the beginning of the fourth national survey of the Chinese materia medica resources, there were 22 provinces have conducted pilots. The survey teams have reported immense data, it put forward the very high request to the database system construction. In order to ensure the quality, it is necessary to check and validate the data in database system. Data validation is important methods to ensure the validity, integrity and accuracy of census data. This paper comprehensively introduce the data validation system of the fourth national survey of the Chinese materia medica resources database system, and further improve the design idea and programs of data validation. The purpose of this study is to promote the survey work smoothly.
