The research on forest ecological product (eco-product) value realization and ecological industry(eco-industry) has become a current hotspot. In order to facilitate scholars’ understanding of the progress of existing research, this paper, based on 286 retrieved documents, statistically analyzes the research content, regional distribution, etc. And the following understandings were obtained: (1) The current volume of publications as a whole shows a trend of steady increase year by year, and China is the country with the largest volume of publications, accounting for more than half. (2) The research content mainly focuses on four aspects: supply capacity assessment, value accounting, value realization mechanism and eco-industry of eco-products. (3) It puts forward the problems of insufficient supply and slow development of industry at the present stage, deepens the deficiencies of the existing research and analyzes its inspiration for the future development of mountain forestation areas in rocky desertification control. Aims at providing forest practitioners and relevant decision makers with information for managing and regulating the supply capacity of forest eco-products and eco-industries. At the same time, it also provides ecological restoration technicians with a path to think about optimizing forest ecosystems for rocky desertification control.

To study the phytoremediation effect of Cd pollution in the riverbed soil around the sewage, the effects of six typical plants, namely Solanum nigrum L (SNL), Phytolacca acinosa roxb (PAR), Nephrolepis auriculata (L.) (NAL), Pogonatherum crinitum (Thunb.) kunth (PCK), Pteris vittata L (PVL), and Sedum lineare Thunb (SLT), on the Cd concentration in the soil with different pollution levels (3, 5, and 8 mg/kg) and the Cd concentration in different parts of the plant (root, stem, and leaf) after planting were studied to explore the remediation effects of different plants on different Cd polluted soils. The research results show that when the concentration of Cd in the soil was 3 mg/kg, the Cd enrichment coefficient of SNL and SLT was the largest. At the same time, the Cd concentrations in the stem and leaf of SNL and the root and stem of SLT are 26.18, 40.26, 34.38, and 49.45 mg/kg, which can be recycled by composting. Therefore, it is recommended to plant SNL or SLT to repair the Cd pollution in the urban residential area. At 5 mg/kg, the Cd enrichment coefficient of SLT was the largest. At the same time, the concentration of Cd in roots and stems was 65.79 and 108.11 mg/kg, which could be reused by composting and hydrothermal transformation. Therefore, it is recommended to plant SLT to repair the Cd pollution in the light industry zone. At 8 mg/kg, the Cd enrichment coefficients of NAL and SNL were the largest. At the same time, the stem and leaf of SNL and the leaf of NAL could be reused by composting and hydrothermal transformation. Therefore, it is recommended to plant NAL to repair the Cd pollution in the heavy industry zone and mix NAL and SNL to repair the Cd pollution in the chemical industry concentration zone.

In the past 10 years, the level of heavy metals has sharply increased in the Jiangxigou farm in the Qinghai Lake basin, which has seriously affected the health of Przewalski’s gazelle. Nano-potassium molybdate (nano-K 2 MoO 4 ), as a new nano-fertilizer, has been applied in agriculture. To study the effect of applying different levels of nano-K 2 MoO 4 fertilization (8 kg/hm 2 , group I; 9 kg/hm 2 , group II; 10 kg/hm 2 , group III) on preventing heavy metal toxicity in Przewalski’s gazelle. The samples of soil, forage, and animal tissues were collected for testing heavy metals and mineral contents, oxidative stress, and blood indexes. The empirical findings showed that the contents of selenium (Se) and copper (Cu) in the tested forage were significantly higher than those in the control group (p<0.01). The levels of Cu and lead (Pb) in the blood and liver of the tested Przewalski’s gazelles were remarkably higher than those in the control animals (p < 0.01), but the levels of molybdenum (Mo) and Pb were remarkably lower than those in the control animals (p < 0.01). The levels of hemoglobin (Hb), platelets (PLT), and red blood cells (RBC) in the tested Przewalski’s gazelles were remarkably higher than those in the control animals (p<0.01). The enzymatic activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT), and total antioxidant capacity (T-AOC) in the serum of the tested Przewalski’s gazelles exhibited a significant increase in comparison to the control animals (p<0.01), but the content of malondialdehyde (MDA) was lower than that in the control animals (p<0.01). In summary, the application of nano-K 2 MoO 4 not only significantly improved the antioxidant capacity and alleviated effectively the anemia symptoms of Przewalski’s gazelle, but also reduced the heavy-metal toxicity of Przewalski’s gazelle in the fertilization areas.
