Application of Remote Sensing Technology in Investigating Planting Area of Paeoniaceae suffruticosa in Shicheng County of Jiangxi Province / 中国药房

ABSTRACT

OBJECTIVE： To provide reference for the development and sustainable utilization of TCM industry with regional characteristics. METHODS： Taking Shicheng county of Jiangxi province as an example， field investigation was carried out on Paeoniaceae suffruticosa planting base in the county， a few representative P. suffruticosa planting bases in the county were selected as sample points， and GPS was used to locate and record the location information of sample points. The remote sensing image was automatically extracted by computer， the artificial visual interpretation method was used to get P. suffruticosa planting area image. Then combined with the field inspection verification， P. suffruticosa planting area was obtained， and the investigation results were analyzed. RESULTS： Through remote sensing interpretation of the planting area of P. suffruticosa in Shicheng county， it was obtained that the total planting area of P. suffruticosa in Shicheng county was 42 597 951.505 square meters （63 864.995 mu） in 2018， accounting for about 33％ of the cultivated land area， which was 42.12％ higher than the conventional planting area of 44 936 mu in 2013. The distribution of P. suffruticosa planting in Shicheng county was mainly concentrated in Xiaosong town and Fengshan town in the north， and Daqu town and Pingshan town in the south. CONCLUSIONS： Remote sensing technology has the advantages of fast data acquisition， large amount of information， high accuracy and strong timeliness， which greatly avoids the complexity of work， saves a lot of manpower and material resources. The technology can provide technology support for obtaining the regional planting area and distribution information of TCM such as P. suffruticosa， dynamic monitoring， scientific warning of the market status of TCM， and guiding the large-scale， standardized and intensive development of TCM cultivation.
