“…After years of effort, genetic variation and phylogenetic relationships in Chinese indigenous pig breeds have been explored morphologically, cytogenetically, and biochemically (Xiao et al, 2010). With the rapid development of molecular biology technology, research on the nuclear DNA diversity of pigs has increased, including RAPD, microsatellite DNA markers, AFLP, DNA fingerprinting, and mitochondrial DNA sequencing (Ren et al, 2000;Chen et al, 2004;Zhao et al, 2007;Wang et al, 2010). However, the majority of genetic data are still poorly characterized, except in a few very famous breeds.…”

Shandong indigenous pig breeds are an invaluable source of data on genetics in Chinese pigs. However, information on the genetic basis of these breeds remains limited. In this study, we used specific-locus amplified fragment sequencing to conduct whole-genome screening to investigate genetic diversity in Shandong indigenous breeds and Western pig breeds. The results showed that Duroc pigs (DD) had clear genetic relationships with Dapulian pigs (DPL; Fst = 0.4386) and Laiwu pigs (LW; Fst = 0.5134), and DPL and LW were relatively close genetically (Fst = 0.2334). In general, Shandong indigenous breeds showed greater genetic variety than the Western breeds. Both neighbor-joining trees and principal components analyses were able to differentiate the breeds, but population structure analyses indicated that the Western breeds genetically influenced the Shandong indigenous breeds to some extent. A total of 162 differentially selected regions (DSRs) with 841 genes and 157 DSRs with 707 genes were identified in DPL and LW, respectively. Gene annotation of the selected regions identified a series of genes regulating immunity and fat deposition. Our data confirm the rationality and accuracy of the current classification of pig breeds in Shandong province. Our results point to candidate genes in Shandong indigenous pig breeds and further promote the importance of follow-up research on functional verification.

“…The system should also conform to the following principles: 1) healthy principles; 2) integrated, identifiable and previously established principles of ecosystems; 3) comparable and feasible properties; 4) selected factors and standards should be sensitive and suitable for the scale of the study area. The assessment index system in the three strata layers for the evaluation of the FHA effect on forests is presented in Table 2, obtained from an AHP method and relative achievements in China (Chen et al, 2002;Kong et al, 2002;Xiao et al, 2003;Huang et al, 2004) and abroad (Ferretti, 1997;Oszlanyi, 1997;Alexander and Craig, 1999;Hale et al, 1999;Dobbertin et al, 2003;Musio et al, 2004;Seidling, 2005;Eisenbies et al, 2006).…”

“…Recent achievements overseas in this aspect largely involves health monitoring methods of entire systems (Ferretti, 1997;Dobbertin et al, 2003;Seidling, 2005), forest structures and their properties (Hale et al, 1999), dynamic data of heavy metals in forest soils (Eisenbies et al, 2006), environmental pollution (Oszlanyi, 1997;Musio et al, 2004) and plantation productivity (Alexander and Craig, 1999). Experts in China have mainly engaged in discussion of concepts and an evaluation index system on the state of health of forest ecosystems (Yuan et al, 2001;Chen et al, 2002;Kong et al, 2002;Xiao et al, 2003;Xu et al, 2005), assessment of forest soils (Huang et al, 2004;Liu J et al, 2005;Shangguan, 2005, 2006), evaluation of the service functions of forest ecosystems (Zhao et al, 2004;Jin et al, 2005) and the effect of actual reservation projects of natural forests on economic and environmental benefits (Liu et al, 2005a). Most results relate to discussion of assessment indices or general research of forest ecosystems.…”

Assessment of the effect of a fully closed hillside afforestation mode on the natural Pinus tabulaeformis forest

Assessment of the effect of a fully closed hillside afforestation mode on the natural Pinus tabulaeformis forest E Higher Education Press and Springer-Verlag 2008Abstract The Huanglong Mountain forest zone is one of the major natural secondary forest zones in the southern Loess Plateau in Shaanxi Province, China. Since 1950, a mode of fully closed hillside afforestation (FHA) has been applied in the forest. On some special sites, the forest age exceeds 80 years. Pinus tabulaeformis forests form the most important vegetation cover in the warm temperate regions of China. Similarly, populations of P. tabulaeformis are dominant in existing forest ecosystems. Quercus liaotungensis, Syringa oblata, Populus davidiana, Prunus davidiana, Betula platyphylla and Toxicodendron vernicifluum can be occasionally found in the tree layer and shrub species are abundant. Based on the data collected from 31 plots and 93 soil samples, the state of health of the forest ecosystem is discussed and the appropriate FHA age has been determined. Twelve indices representing vegetation and soil properties in natural, secondary P. tabulaeformis forest ecosystems were generated by sensitivity analysis and an assessment index system for the FHA mode was established. According to the equal distance method, a clustering technique and five grades of an integrated index for evaluating the FHA mode were compartmentalized. The effect of the FHA mode on natural secondary P. tabulaeformis forests was evaluated by an integrated index method with the aid of an analytical hierarchy process (AHP). The results are as follows: values of the integrated index in the FHA mode of 16, 25, 30, 45, 60 and 75 year old stands were 7.25, 6.88, 7.82, 5.51, 4.78 and 2.79 respectively. With an increase over age of the FHA stands, the effect of the FHA mode deteriorated. We conclude that natural forests should not be protected in the FHA way after 45 years. At that stage, mixing suitable tree species, selection cutting and other silvicultural and management measures should be adopted.

“…Besides, the effects on human health and social value are also considered important parts of ecological health concept (Yuan et al 2001;Cui and Yang 2003;Hu et al 2005). To date, ecosystem health studies have been carried out on forests (Chen et al 2002;Xiao et al 2003), wetlands (Cui and Yang 2003;Jiang et al 2005), rivers (Hui et al 2011;Einheuser et al 2012;Yu et al 2014), soils (Bai et al 2011;Gao et al 2013;Huang et al 2013), grasslands (Tong et al 2009;Zhang et al 2015), lakes (Jørgensen 1995a;Zhao et al 2005;Kane et al 2009;Xu et al 2012) and urbans (Zhou and Wang 2005;Liu et al 2008;Song and Xu 2011;Zhao and Chai 2015).etc. Since the concept of ecosystem health emerged and set new goals for environmental management in 1980s, the health of lake ecosystem has socially and academically become one of the hot issues and common concerns (Xu et al 2001;Kane et al 2009;Zhang et al 2010;Xu et al 2011).…”

As lake ecosystem assessment is the foundation to achieve lake monitoring, environmental management and ecological restoration, a new concept of lake ecosystem health and driving force-pressure-state-impact-responsemanagement framework was proposed to find out the causal relationship of the system and health distance model was taken to represent the health level of ecosystem. An assessment indicator system comprised of water quality, ecological and socio-economic criteria was established. The evaluation models were applied for the assessment of the ecosystem health level of a typical lake, Nansi Lake, China. Depends on the values of health distance, the heath level was described as 5°: very healthy, healthy, general healthy, sub-healthy and diseased. Using field investigation data and statistic data within the theory and applied models, the results of comprehensive assessment show that: (1) the health distances of water quality indicators, ecological indicators, socio-economic indicators and comprehensive health distance were 0.3989, 0.2495, 0.4983 and 0.4362, respectively. The health level was in general healthy condition. Ecological indicators were in healthy condition, which indicate that the stability was high. The distance of water quality had shown a tendency to approach general healthy level. As the health distance of socio-economic indicators have shown a bad impact form human beings, more effective measures need to be developed. (2) The results of a case study demonstrated that the methods in this paper provide a similar result corresponding with the actual lake health condition. Therefore, this paper shows that the proposed method is efficient and worths generalization.
