Core Insights - The Xinjiang Uyghur Autonomous Region's Natural Resources Department and the Xi'an Geological Survey Center have completed a comprehensive soil geochemical survey in southern Xinjiang, covering nearly 210,000 square kilometers over nine years, identifying 54 elements and indicators in the soil [1][2] - A significant finding is the discovery of a "selenium belt" stretching nearly 1,000 kilometers along the southern Tianshan Mountains, with 4.9 million acres of selenium-rich land, including 1.13 million acres of selenium-rich farmland, accounting for 27% of the arable land in southern Xinjiang [1][2] Group 1 - The soil geochemical survey focused on oasis areas, collecting 24,000 data points on nutrient elements, heavy metals, and health-related elements, resulting in the most systematic and spatially precise soil geochemical mapping data for southern Xinjiang to date [1] - The survey identified that 10% of the certified selenium-rich land in China is located in five areas of southern Xinjiang, totaling nearly 300,000 acres [1] - In addition to selenium, the survey found that calcium and magnesium-rich lands cover 99.3% and 91.8% of the oasis area, respectively, while molybdenum-rich land accounts for 20.2%, primarily in the Aksu-Kuerle region [1] Group 2 - Based on over 2,000 samples of plants and animals, the survey identified 22 types of selenium-rich products, including three grain crops (wheat, rice, corn), seven fruits and vegetables (fresh chili, fresh tomato), three livestock products (eggs, chicken, beef), and two spices (garlic, cumin) [2] - The survey data covers 97% of the arable land in southern Xinjiang, with all farmland classified as alkaline soil, of which 33.4% is strongly alkaline; 99.8% of the soil is classified as priority protection clean soil [2] - The soil nutrient evaluation indicates that the total phosphorus and potassium content is primarily moderate to rich, with 908,100 acres of high-quality farmland and 2,102,700 acres of suitable soil for green food production identified, mainly in the Yarkand Basin, Kuqa Basin, along the Aksu River, and western Kashgar [2]

对话人： 韩宗峰 本报评论员 范 进 盐阜大众报评论员 韩宗峰：在长三角一体化发展的国家战略大棋局中，盐城积极探索"飞地经济"发展模式，为区域协同发 展注入新动能。请问，何谓"飞地经济"，盐城发展"飞地经济"有哪些独特优势？ 范进："飞地经济"是指两个相互独立、经济发展存在落差的行政地区打破原有行政区划限制，通过跨空 间的行政管理和经济开发，实现两地资源互补、经济协调发展的一种区域经济合作模式。盐城发展"飞 地经济"优势显著。大丰区拥有307平方公里的"上海飞地"，是上海域外最大的农产品生产加工和产能合 作基地，为沪盐合作奠定了坚实基础。 同时，盐城是苏北唯一被纳入长三角中心区的城市，拥有深水良港、河海联动优势以及大量成片建设用 地，在承接产业转移、发展临港产业等方面潜力巨大。去年，盐城市纵深推进区域合作，加快融入新发 展格局，成功跻身上海大都市圈，中山医院苏北健康管理中心正式运营，沪苏、常盐、苏盐合作园区项 目加快集聚，新开工来自长三角地区亿元以上项目530个。 韩宗峰：盐城目前有哪些"飞地经济"项目，发展现状如何？ 范进：盐城目前有多个"飞地经济"项目，其中沪苏大丰产业联动集聚区为核心抓手。沪苏大丰产业联 ...
