Our country is accelerating the development of biomass energy to supplement its energy supply. In 2007, Hebei Province planted 50,000 mu of Chinese tallow tree; this plant, known as the \"diesel tree\", produces biodiesel from its seeds that is very similar to conventional diesel. This effort to supplement energy supplies will continue, with Hebei Province expected to plant another 50,000 mu of Sophora japonica this year. Planting Sophora japonica in Hebei Province is part of China’s biomass energy development plan. In 2006, China launched the construction of biomass energy bases. **The Forestry Bureau has signed a framework agreement on integrated oil and forestry cooperation with CNPC, aiming to establish 6 million mu of demonstration bases for oil-bearing energy forests across the country within 5 years. In 2007, 1 million mu were planted across 7 provinces, with Hebei taking on the task of planting 50,000 mu of Sophora japonica. China is the world’s second-largest producer and consumer of energy, with its dependence on imported oil approaching 50%. Since 2003, China’s GDP has maintained a growth rate of over 10%, resulting in an increasing demand for energy. Adjusting the energy structure and vigorously developing new and renewable energy sources, including biomass energy, has become a strategic measure to ensure **energy security. On September 4, 2007, the **Development and Reform Commission officially released the Medium- and Long-Term Development Plan for Renewable Energy**, setting a goal to have the consumption of renewable energy sources such as solar, wind, geothermal, oceanic, and biomass energy account for around 10% of the total energy consumption by 2010, and around 15% by 2020. The annual production capacity for biodiesel was aimed to reach 2 million tons. It is reported that research and development of biodiesel in China are progressing rapidly, and the technologies for converting the seeds of Jatropha, Casuarina, and Melia to biodiesel are already quite mature. In recent years, China has successively built many biodiesel plants with an annual production capacity of over 10,000 tons. In the mountainous areas of Hebei Province, Sophora flavescens is a native tree species that is widely distributed there. According to statistics from the forestry department of Hebei Province, there are 300,000 mu of Sophora japonica naturally distributed across the province. To increase planting efforts, the forestry department has expanded the cultivation area of Chinese ash from mountainous regions to plains. Experiments have shown that trees grow well in these plain areas; therefore, Chinese ash will also be planted extensively on unused land in the plain areas of Hebei Province in the future. Currently, enterprises in Hebei that utilize biomass energy to produce biodiesel are also beginning to emerge. It is reported that Wangdu County in Hebei Province is using foreign investment amounting to 50 million yuan to build a factory ； Guantao County and Tangshan City are in the process of preparation ； The Wu’an, Jinzhou, and Shijiazhuang refineries have been built and put into operation. The forestry department of Hebei Province stated that by 2010, the province would establish 1 million mu of bases for forestry biomass energy raw materials, capable of supplying 60,000 tons of biodiesel raw materials per year. By 2020, 3 million mu are to be planned and developed, providing 500,000 tons of biodiesel raw materials per year. By 2050, 10 million mu are planned to be developed, providing 5 million tons of biodiesel raw materials per year. According to estimates by the **Forestry Bureau, China currently has approximately 300 million tons of raw materials that can be used for forestry biomass energy production, which is equivalent to about 200 million tons of standard coal. The total area of woody oil-bearing tree species across the country exceeds 4 million hectares; there are 154 plant species whose seed oil content is over 40%, and the fruit production amounts to more than 4 million tons. At present, China still has over 54 million hectares of uncultivated mountainous and barren land suitable for afforestation. There are also nearly 100 million hectares of saline-alkali land, sandy land, as well as land reclaimed from mines and oil fields that is not suitable for farming; most of this land is appropriate for cultivating specific energy forests.
