It lies between 31°50″–32°45″ north latitude and 106°27″–107°10″ east longitude. The region is longer from north to south than east to west, covering an area of 3,417 square kilometers with a forest coverage of 47%. The elevation ranges from 370 to 2,508 meters, featuring steep and narrow mountain ridges, deeply cut valleys, and vast expanses of barren hills, wasteland, and sloping farmland. The soil is mainly composed of purple soil, yellow soil, and yellow-brown soil. The climate is moist while the soil is relatively dry, with an average annual temperature of 16.2°C, a frost-free period of 259 days, an average annual accumulated temperature of 5,096°C, average annual rainfall of 1,161 mm, annual sunshine duration of 1,570 hours, and relative humidity of 64–79%. The area suitable for walnut cultivation, capable of achieving high, stable, and premium yields, spans 20,000 hectares, making it the most ideal region for developing the walnut industry.

　　Nanshan County has a long history of walnut cultivation. In the late 1960s and early 1970s, it was one of the top five walnut production bases in China and earned the reputation as the “Hometown of Chinese Walnuts.” KGZ Sichuan Flavor Sichuan Food Network

　　Walnuts, also known as Persian walnuts, belong to the division Angiosperms, class Dicotyledons, family Juglandaceae, and genus Juglans. In Nanshan County, there are four main types distributed: common walnut, iron walnut, wild walnut, and Juglans mandshurica. These are widely found at altitudes between 400 and 1,800 meters and are ideal economic tree species for mid-altitude mountainous regions, being drought-resistant, thin-soil-tolerant, and averse to waterlogging and high temperatures.

　　The introduction of walnuts to Nanshan began in the Han Dynasty and has a history of over a thousand years. By the 1970s, the industry had reached a considerable scale and gained fame both within and outside the province, with the capacity to export 400–600 tons. Currently, the county has formed a major walnut-producing region with 800,000 bearing trees, covering approximately 50,000 mu, producing 1.5 million kilograms of walnuts annually and generating an output value of 7.5 million yuan. In 2010, total production reached 10 million kilograms, with a total output value of 130 million yuan (including processing value), creating a profit tax of 4 million yuan. Coupled with years of accumulated rich production and management experience among local forest farmers, this has laid the foundation for walnut industry development and initially established the star-quality advantage of “Nanshan Walnuts.” KGZ Sichuan Flavor Sichuan Food Network
