Biomass structure analysis of Atractylodes lancea in different ecological environments / 中国中药杂志

<p><b>OBJECTIVE</b>To study the ecological environments of Atractylodes lancea by biomass structural analysis.</p><p><b>METHOD</b>Through the scientific investigation in Maoshan, the sampling spots were set up, the relation between growth and ecological environments was researched and the ecological environments of A. lancea were divided as following: the vegetation layer, the shrub layer, the shrub-weed layer and the weed layer. The ramet biomass, height, leaves and coverage of A. lancea were studied.</p><p><b>RESULT</b>The several factors (ramet biomass, height, leaves and coverage) showed the regular change. Among maximum, minimum and average, the shrub layer was the biggest, the shrub and weed layer was the second biggest and the vegetation layer and the weed layer was the least.</p><p><b>CONCLUSION</b>A. lancea tends to distribute in the shrub layer and the shrub-weed layer.</p>

Remote sensing resource monitoring on Atractylodes lancea / 中国中药杂志

Remote sensing technology was used for investigation of the resources of Atractylodes lancea. Firstly, the general situation of Jiangshu Maoshan and A. lancea in Maoshan was introduced; Secondly, the methods of remote sensing on the resource of the wild drugs were explained. Thirdly, the TM images were interpret according to the differences of the objects reflex spectrum, and growth environments in Damao mountain, Ermao mountain and Xiaomao mountain were divided into different sub-areas according to the results of the field investigations. Finally, the resource of A. lancea in Jiangshu Maoshan was estimated.

Comparing of different methods on habitat adaptive division of Chinese material medica / 中国中药杂志

<p><b>OBJECTIVE</b>To comparing two kinds habitat adaptive division of Chinese material medica with different models.</p><p><b>METHOD</b>The habitat adaptive divisions of A. lancea according essential oil accumulation with two kinds pattern, model pattern and template pattern were carrid and compared.</p><p><b>RESULT</b>Two habitat adaptive divisions of A. lancea maps according essential oil accumulation were gotten.</p><p><b>CONCLUSION</b>Both model pattern and template pattern were efficient on habitat adaptive division of Chinese material medica, but they shoud bu used with different processesd and based different background [corrected]</p>

Remote sensing monitoring methods for medicinal plants resource in different types of ecological environment / 中国中药杂志

Different remote sensing monitoring methods are needed for the medicinal plant resource in different types of ecological environment. This paper explained remote sensing monitoring methods for the resource of the wild medicinal plants and cultivated plants, and analyzed the rare species, generous species and species in special ecological environment in detail. It provides a new method to all kind of medicinal plants resources' remote sensing monitoring.

Key influencing factors on essential oil components of Atractylodes lancea and study on its division of climate adaptability / 中国中药杂志

<p><b>OBJECTIVE</b>To find the key factors that influence the content of the essential oil components of Atractylodes lancea and classify the habitat of A. lancea based the essential oil components, as well as explore a new method to conduct division of Chinese natural medicin through geographic information system (GIS) ultimately.</p><p><b>METHOD</b>The key factors were obtained by canonical correlation and stepwise regressive analysis. Then the interpolation of climatic data for 30 years (1971-2000) was done by Sufer 7.0, and the habitat division was done by ARCGIS 9. 0.</p><p><b>RESULT</b>There were 6 correlation models between climate factors and 6 main essential oil componets were obtained, and a division map about essential oil components content of A. lancea base on clamate adaptability were drawn. It was found that the climate condition in Octobers played a key role on forming the essential oil components and the interaction of tempreture and precipitation was the most important factor on forming the essential oil components of A. lancea.</p><p><b>CONCLUSION</b>The adaptive habitat for forming the essential oil components of A. lancea was different from growing A. lancea ones. And GIS can be used perspective for division of Chinese natural medicine.</p>

Application of multivariate statistical methods in research of Chinese medicinal materials resource ecology / 中国中药杂志

In this paper the application of multivariate statistical methods in research of Chinese medicinal materials resource ecology was introduced. The importance of multivariate statistical analysis used in research on analyzing ecological environment factors and region suitability of Chinese crude drugs has been pointed out. Several frequent used multivariate statistical methods have been presented.

Study on dynamical changes of Ginkgo biloba resources in Pizhou city of Jiangsu Province base on RS and GIS / 中国中药杂志

<p><b>OBJECTIVE</b>To analyse the dynamical changes of the Ginkgo biloba's resources from 2001 to 2006, in Pizhou city, Jiangshu province by useing spatial analytical function of GIS and RS technology.</p><p><b>METHOD</b>Use the GIS and RS technology, extracted the information of G. biloba by scientific investigation, researched the spatial distribution and dynamical changes of G. biloba based on landsat 5 TM: the Apr. 3rd, 2001; Jan. 16th, 2005; July 30th, 2006.</p><p><b>RESULT</b>Ginkgo biloba's resource was 1.61 x 10(5) hm2 in 2001, 1.84 x 10(5) hm2 in 2005, 1.88 x 10(5) hm2 in 2006.</p><p><b>CONCLUSION</b>Ginkgo biloba's resource rised from 1.61 x 10(5) hm2 to 1.88 x 10(5) hm2 from 2001 to 2006, showed the gradually rise.</p>
