The main afforestation model of returning land for farming to forestry project in Hunan;

Implementing program of converting land to forest started in 2001 in Yiling district of Yichang city since 5 years, the afforestation models complying with the local actual advanced and suitable 5 afforestation models were screened out through the study and application with the afforestation models of the whole district.

Several afforestation models, advanced and adaptable to local conditions, have been achieved through study for the returning crop plots to forestry in Ordos area.

Study On Forestry Sustainable Development Afforestation Mode of Zhumadian City;

Study on the afforestation mode of the returning land for farming to forestry in Hunan;

Study on Afforestation Mode in Shanxi Province——Study on site type division and afforestation mode in Shanxi Province(Ⅱ)

On the analysis of the natural, social and economic condition of Diqing Prefecture combined with local regional climate characters, the project layout of forest rehabilitation from slope agriculture, tree species selection and afforestation patterns are proposed, while the effects of the project achievements are analyzed.

Evaluation on Plantation Model of State Forest Farms in Henan Sandland Area and Its Development Trend;

Ten Types of economical-ecological plantation models for grain for green project implementation in Yuyang district were introduced in light of local geography,climate,soil and vegetation conditions.

The thesis studies the soil ecological function of water conservation forests and discusses the optimal afforest models in HuangPu jiang River Basin, the results are described as follows: (1)Organic matter content, total nitrogen content, available phosphorus and potassium content reduce obviously with depth of the soil in each plot, but PH value increase obviously on the contrary.
