Protection and management:through the development of effective policies to improve standardized planting herbs, the introduction of advanced equipment and technology, so that the protection and exploitation of combining achieve conservation and management objectives. At present, in order to protect wildlife resources, while expanding production of medicinal plant resources, we need to greatly strengthen the development of medicinal herbs cultivation industry. Lingui District herbs cultivated existing industry has begun to take shape, with a base area Chadong Township Mangosteen 1716 hm2, other herbs base has 1114 hm2. Combined with the existing policy and the villages policy terrain, soil, water and heat conditions, according to the distribution of medicines village, village-level plans drawn Lingui District 11 kinds of herbs 100 dministrative villages, to guide further planning has a medicinal plant greater significance.
