TITLE:
摘要: 目的:为实现地区特色中药材产业发展与可持续利用提供参考。方法:以江西省石城县为例,对该县白莲种植基地进行实地调查,选取县域内少数具有代表性的白莲种植基地为样点,利用GPS进行定位,记录样点位置信息。利用计算机自动提取遥感影像,并采用人工目视解译法得到白莲种植区域图像,再根据实地考察验证,得到白莲种植面积,并对调查结果进行分析。结果:通过对石城县白莲种植面积遥感解译,得到2018年其种植总面积为42 597 951.505平方米(63 864.995亩),约占耕地面积的33%,相比2013年统计的白莲种植面积(44 936亩)增长了42.12%。石城县白莲种植分布情况为县城以北,主要集中在小松镇和丰山镇,南部则以大曲乡和屏山镇种植较多。结论:遥感技术具有数据获取速度快、信息量大、准确度高且时效性强等优势,极大地避免了工作复杂性、节省了大量人力、物力。该技术可为获得区域中药材如白莲的种植面积及分布信息,动态监测、科学预警中药材市场状态,引导中药材种植向规模化、规范化、集约化发展提供技术支持,从而有效防范中药材产业市场风险。
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.
