本数据含塔吉克专家采集的蝗虫发生点与蝗虫轨迹。含以下属性：大区、地区、时间、是否蝗虫、latitude、 longitude、蝗虫种类、受灾面积、迁飞轨迹。共275个样本。\n
本数据集为塔吉克专家采集的塔吉克斯坦蝗虫入侵历史记录，每条记录包含9个字段：oblast_en（州）、rayon_en（区）、date（调查日期时间，格式YYYY-MM-DD HH:MM:SS）、 has_locust（是否有蝗虫）、latitude（纬度）、longitude（经度，均为十进制坐标，精确至小数点后4位）、locust_species（蝗虫种类）、area_infested_m2_sum（受侵面积，单位：平方米）、raw_flying_direction_values（飞行方向）。", "ds_source": "
数据来源于塔吉克斯坦专家（塔吉克斯坦国家科学院动物与寄生虫研究所）提供的蝗虫发生点与迁移轨迹调查记录，基于野外实地调查获得蝗虫发生的位置坐标、发生种类、受侵面积及迁飞方向。", "ds_process_way": "
原始野外调查记录整理为Excel表格，字段统一采用英文命名（州、区名称转写为英文），坐标转换为十进制经纬度，蝗虫种类以标准代码（CIT、DMA、LMI）标注，受侵面积按平方米汇总，飞行方向保留原始记录值。", "ds_quality": "
州、区、日期、经纬度、蝗虫种类、受侵面积等核心字段记录完整，未发现空值，也未发现完全重复的整行记录 。但存在以下需注意之处：飞行方向字段存在大量空值，迁飞轨迹信息仅部分记录可用。", "ds_acq_start_time": "2016-07-11 00:00:00", "ds_acq_end_time": "2024-10-23 00:00:00", "ds_acq_place": "Sogd（粟特州）,Khatlon（哈特隆州）,Tadzhikistan Territories（塔吉克斯坦中央直辖区域）", "ds_acq_lon_east": 70.70666666666666, "ds_acq_lat_south": 37.22361111111111, "ds_acq_lon_west": 67.95777777777778, "ds_acq_lat_north": 40.715833333333336, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "apply-access", "ds_total_size": 3150732, "ds_files_count": 3, "ds_format": "*.xlsx", "ds_space_res": "", "ds_time_res": "日", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "c0081068-d56b-4af1-96d4-159bd905d073.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "b6ee8072-db07-4053-bcbc-78e22d72c5ec", "ds_serv_man": null, "ds_serv_phone": null, "ds_serv_mail": null, "doi_value": "", "subject_codes": [ "210" ], "quality_level": 0, "publish_time": "2026-10-14 15:19:48", "last_updated": "2026-10-14 15:19:48", "protected": false, "protected_to": "2027-09-05 00:00:00", "lang": "zh", "cstr": "11738.11.ncdc.db7831.2026", "i18n": { "en": { "title": "Dataset of Locust Invasion Timing, Distribution, and Trajectories in Tajikistan (2016–2024)", "ds_format": "*.xlsx", "ds_source": "
